Comments about Roto Grip Roto Grip Mutant Cell:

Found this ball does not have the finishing power of the Cell. Not as good a ball as Roto Grip usually makes.

Comments about Roto Grip Roto Grip Mutant Cell:

Comments about Roto Grip Roto Grip Mutant Cell:

Great hook, very smooth, good for those first two game, when the lane are the oiliest !

Comments about Roto Grip Roto Grip Mutant Cell:

This ball was great out of the box. It had a good overall hook. Great midlane read, excellent backend, and it hit HARD. However, after a month or so the ball just stopped coming in. In other words, this ball requires A TON of maintenance. If you do not keep it clean and take good care of it (including rejuvenating and sanding), the ball will die out very quickly. If you don't put the time and effort into keeping the ball well-maintained, you'll end up with a [$]spare ball like me.

Comments about Roto Grip Roto Grip Mutant Cell:

For the first 3 months I used this ball my average jumped 25 pins and my high game was a 259. Wow I am only a 155 avg. bowler. Then I started struggling with the ball to get it to hook. Now I have to soak it in hot water and Dawn every 9 games to keep it kind of working but it has never been as good as it was when new.

Comments about Roto Grip Roto Grip Mutant Cell:

i have thrown this product on the oil pattern called 'Highway to hell." it reacts really nice. just need to be carefully not to put it out too far. if you pull it its almost a gurantee that it will end up on the brooklyn side.

Comments about Roto Grip Roto Grip Mutant Cell:

Ball works great right out the box, but after about 9 games it stop hooking. I cleaned it after each series.

Comments about Roto Grip Roto Grip Mutant Cell:

I am a league bowler with a 160 average. this is the second roto grip ball i have, its a great ball hooks when you least expect it to on the lanes which is great for flat lanes. this is my heavy oil ball and i have a rotogrip rogue cell to go with it! this ball is just amazing my average has gone up 15 pins since i got this ball!

Comments about Roto Grip Roto Grip Mutant Cell:

This ball is great on almost any lane condition! Today i was doing okay, with my cell pearl and decided to pull this out and ended up throwing a 300. im only 17, but needless to say Roto Grip is amazing and i would recommend any ball they come out with!!

Comments about Roto Grip Roto Grip Mutant Cell:

This ball didn't work so great out of the box had the ball polished and ever since its been great. I shot my first 700 series with this ball and im looking forward to get another Roto Grip ball. This ball has an amazing backend and works great on Sport shots.

Comments about Roto Grip Roto Grip Mutant Cell:

Great ball. Love it. Glad I made this selection. My average has improved from 130 to 160-180.

Comments about Roto Grip Roto Grip Mutant Cell:

I just drilled this ball a week ago. Great continuation through the oil. A bit strong in the midlane, but that's what most bowlers need on the long heavy oil patterns. Ok to use on a house shot, might want to change the surface a bit though.

Comments about Roto Grip Roto Grip Mutant Cell:

i am 75 yrs old.3weeks after i purchase the mutant cell,i bowled a 300 game and a 770 series.i would buy another.

Comments about Roto Grip Roto Grip Mutant Cell:

Sweet... Awesome... Perfect for any oil condition... Simply amazing.

Comments about Roto Grip Roto Grip Mutant Cell:

not a good ball. i have bowling balls 5 years old that hook harder

Comments about Roto Grip Roto Grip Mutant Cell:

The ball has given me a options and a line that I was never able to shoot before.

Comments about Roto Grip Roto Grip Mutant Cell:

When I purchased the Mutant Cell I was looking for something with an aggressive backend into the pocket and that is exactly what I got. Threw 249 my very first time rolling it on a medium oil house shot. When you hit you mark with this ball, it comes hard at the pins like they gave it a dirty look...big mistake on their part.

Comments about Roto Grip Roto Grip Mutant Cell:

I am enjoying getting use to the more hook than I had on my previous ball. I love the solidness of a pocket strike.

Comments about Roto Grip Roto Grip Mutant Cell:

This ball finds the pocket from lines I've never been able to shoot before. I've even started picking up a few tough splits with the extra ball movement through the finish. I've had it for 3 days now, bowled 12 games and averaged 223. I haven't stopped smiling for 3 days. Way to go Roto Grip!!

Comments about Roto Grip Roto Grip Mutant Cell:

I'm a 175 average bowler that just took up bowling again after a 20 year break. I got my ball in the mail yesterday, had it drilled and bowled 201, 212, 231 & 244 for a 222 average. I ordered the 16 pound ball and only had one split and was tapped twice in 4 games. I've been averaging 2-4 taps per game and at least 1 split per game for the last 6 months. GREAT BALL. I'm ready to join a league again.

Comments about Roto Grip Roto Grip Mutant Cell:

The ball is awesome! Best dang ball I've owned! However I have one question: How do I throw the mutant cell on wood lanes? I have my State tourney coming up this weekend and would like any advice anyone can give me!

Comments about Roto Grip Roto Grip Mutant Cell:

This ball was great out of the box and gave me a few big series including an 813 right after i got it and a 289 on the scorpion. Soon after though I found this ball to lose its surface and become a spare ball unless I slowed my speed a couple of miles per hour. No matter what I tried to do including changing surface back to factory finish and trying a different layout, I did not find this ball to give me the same reaction on the lanes or pin action in general. This ball does remain great for people with slower ball speeds, but for those of you who throw it above 17 or 18 mph, use it wisely!

Comments about Roto Grip Roto Grip Mutant Cell:

After reading several reviews, I decided to give this ball a try. I only throw roto equipment, carry a 218 average, and this is the biggest disappointment I have come across. I have two mutants; one drilled 5X3 with a 3 inch pin buffer and the other is drilled 4X4 with a 2 inch pin buffer. Regardless of the lane conditions, this ball just will NOT move at all. Maybe its the curse of the lefty, but this is the only Roto ball that I have ever been disappointed in.

Comments about Roto Grip Roto Grip Mutant Cell:

Picked up the ball 30 mins before the league...had doubts using it out-of-the-box, but glad i did -- got 222 first game. The ball seems angry at the pocket (1 & 3 pins) when it hit, it shatters the entire set (5x in a row)...I cannot believe my eyes -- got 709 series with this ball...I think I will buy another one, but will drill it for Dryer/lighter oil lane.

Comments about Roto Grip Roto Grip Mutant Cell:

This has to be one of the worst balling balls I have ever thrown. Ball hooked a ton out of the box within 30 games the ball stopped hooking. I've cleaned the ball the way rotogrip says it has to be cleaned and still can't get it to hook. Very disappointed in this ball

Comments about Roto Grip Roto Grip Mutant Cell:

I would recommend shining the surface of the ball to avoid over reaction. I have a high rev rate and tend to throw the ball pretty fast. A little slower speed and this ball definitely gets the pin reaction you want. Make sure you clean the oil off the ball after bowling because it tends to absorb alot during use and loses a bit of its reaction down the lane. Other than that, great ball!

Comments about Roto Grip Roto Grip Mutant Cell:

Just moved to the Mutant from a Jigsaw. Night and day difference. Mutant grips the lane and makes a strong move to the pocket even without high revs.

Comments about Roto Grip Roto Grip Mutant Cell:

I REALLY LOVE THIS BALL I IMPROVE MY GAME 100% I HAVE ALL THE CELLS AND I LIKE THIS ONE THE BEST.

Comments about Roto Grip Roto Grip Mutant Cell:

Wish I would have had it drilled for more hook. It is very forgiving and the reaction is very predictable. What a reaction it is. The back end will wash out the pins that will stay standing with other balls. Takes a few games to break in. Don't give up to quick on this one. You won't regreat it.

Comments about Roto Grip Roto Grip Mutant Cell:

first night of league with the Mutant Cell and shot 750. Second highest series other than the 809 I bowled earlier. Great surface, tons of hook and I am between 18.5 and 19.2 mph.

Comments about Roto Grip Roto Grip Mutant Cell:

744 out of the box surface, I've polished it and it's simply a beast. The graphics are not concerns when the ball hits like a truck.

Comments about Roto Grip Roto Grip Mutant Cell:

I drilled my Mutant this afternoon feb 16, and played 4 series just to try it out. I'm not a pro my averaged is 190 i the league I did 832 without any effort at least thats how I experienced it. My layout on the ball is a Roto-Grip standard 4 inch pin from pap 1.5 inch thumbhole from massbios as it is shown in their layout chart for asymmetric balls. It worked out well for me I thought the roll was consistent with a twist in the backend supernice. I love this ball already.

Comments about Roto Grip Roto Grip Mutant Cell:

This is a great bowling ball, hooks more than the Rogue. I bought it before league play and bowled with it in league. Results were great 277-252-236=765. The ball hits great and carried light hits as well. Another great ball from Roto Grip. I also have the Cell Pearl and the Rogue Cell.

Comments about Roto Grip Roto Grip Mutant Cell:

I was bowling an average of 180, now with the Mutant Cell coming in at 240 average is just out of this world.

A must have ball!!!

Comments about Roto Grip Roto Grip Mutant Cell:

After trying the Storm Virtual energy and watching my agerage drop 10 pins for 227 to 217 I picket this gem up. I shined it out of the box and wow, never had a ball so easy to rev and hit so well. I have never really had a big game with any ball out of the box but had a 300 with this one after only 12 games. Since bowling is %80 percent mental the confidence you will gain from the Mutant will surly have you paying it off with the jackpot money you win with it. Just get it!

Comments about Roto Grip Roto Grip Mutant Cell:

I got the ball drilled and went right to league play with it and the first game I shot was a 252. I am USUALLY just a right up the second arrow kinda guy, but this ball makes me look like a PRO!!! The way I was swinging it I was amazed. Its like it had a magnet right to the pocket and crushed it. The only problem I had was after the first game the oil was gone so I had to move left even more.Just dont be afraid keeping moving left IT WILL COME BACK.ALL IN ALL I CAN'T WAIT TO GET BACK ON THE LANES.

Comments about Roto Grip Roto Grip Mutant Cell:

Well, I was struggling to maintain a high 220+ average, just couldn't consistently get the big games. I tried another bowlers Cell and liked the reaction, so I purchased a Mutant Cell, hit it with just a little polish and off I went. On Dec.8, I shot 299 and 805 in my first league set with the Mutant, and haven't looked back since. I raised my average to 235 with the help of this balls great hitting power, as it is clean through the heads and doesn't stop once it makes the turn. I was carrying tens pins that should have never fell, and ripping the rack on light hits. Heck, even tripped a few 4 pins. I have found that with my ball speed(higher) that slightly dulled the Mutant is clean down the lane with plenty left.

Comments about Roto Grip Roto Grip Mutant Cell:

Overall very good ball....rolls up real early and has great continuation that blows through the pin deck...Only negative i can say is that over a short period of time of purchase the balls overall hook potential depletes very quickly;however it still maintaines its hitting power which is the best thing about a ball anyways

Comments about Roto Grip Roto Grip Mutant Cell:

1st time buying a ball in a long time , usually i get the hand me downs from my 24 yr old son who averages 235 , i avg 210 using his equipment @ 15lbs but i throw hard , i usually use 16 lbs but since i was getting hand me downs i just didnt care ...until now i broke down and bought the MUTANT CELL WOW! 1st night of bowling i shot 269-222-257-747 a great night i reccommend this ball highly......BIG D

Comments about Roto Grip Roto Grip Mutant Cell:

I PICKED THIS BALL UP TONIGHT AND BOWLED A COUPLE GAMES WITH IT AND THIS BALL IS AMAZING..I WAS 3 TO 4 BOARDS LEFT OR RIGHT OF MY MARK AND IT SEEMS LIKE THIS BALL KNOWS WHERE THE POCKET SHOULD BE...THIS BALL IS AWESOME ON THE BACKEND...THIS BALL IS JUST AMAZING...

Upgrade from my Hammer Anger. Loving this ball.

Comments about Roto Grip Roto Grip Mutant Cell:

190's tweener league bowler has already started to see improvement in limited use. Ball hits like a ton of bricks!

Comments about Roto Grip Roto Grip Mutant Cell:

I'm a tweener. Had to polish it up to keep it in the pocket. Still it hits like a locomotive. Best ball I have ever owned. Last time out shot 258,258,279 in tournament.

Comments about Roto Grip Roto Grip Mutant Cell:

Little hard to control at first. Had to lighten my grip, but it hits the pocket like a train.

Comments about Roto Grip Roto Grip Mutant Cell:

I am 76 years old and have yet to hit under 600
with this ball. I bowl in four leagues a week
including a travel league.

Comments about Roto Grip Roto Grip Mutant Cell:

First time league bowler playing at a heavy oil pattern establishment. A beginner with a 140 average, I'm seeing improvement every time I play, and slowly elevating scores. Good movement, strong backend finish, powerful strike ball. Still working on consistency, and this is an excellent tool to become a great bowler!

Comments about Roto Grip Roto Grip Mutant Cell:

I just bought this bowling ball a few days ago and I can't stop talking about it. It seems when the ball turns the corner it picks up more steam and just crushies the pocket. I have the Virtual Gravity and this ball just out powers the Gravity by a long shot.

Comments about Roto Grip Roto Grip Mutant Cell:

roto grip has done it again i have the whole cell line each one gets better 210 avg 3 sets with this ball to date 729 668 730 with a 300 thanks roto grip great piece

Comments about Roto Grip Roto Grip Mutant Cell:

i'm a third year junior at monmouth university and this is the second year roto grip sponsors us. this year i chose to receive the mutant cell. this is by far the best ball for me to use on any fresh condition, whether it is a typical house pattern or a more challenging pattern. even though the ball has surface out of the box to react earlier than most high performance, it still builds up enough energy to have a strong angular backend reaction to push through the pins. the mutant cell is definitely a ball to have for a any bowler looking to go to the next level

Comments about Roto Grip Roto Grip Mutant Cell:

This is the second bowling ball I have received from Monmouth University's sponsorship, and once again, Roto Grip has delivered. In order to compliment my Original Cell (see review), i got my Mutant drilled with Mo's famous double-thumb layout, Pin 4" from my PAP above the bridge with a balance hole through the RG placed 1 1/2" away from the thumb. The ball is meant to hook out of the building and that is exactly what it does. When I go to a college tournament and the lanes are flooded, I find myself playing through the fresh heads with this ball with ease as the ball reads the lanes and bites hard almost as if I were bowling on a typical house pattern (no joke). The reputation of aggression that the Cell line has holds true with its newest edition, the Mutant Cell.

Comments about Roto Grip Roto Grip Mutant Cell:

ball is drilled 4x4 with 2" pin buffer, strong reaction super hit. Not the best looking ball on th rack but a great compliment to my rogue cell.

Comments about Roto Grip Roto Grip Mutant Cell:

This ball hits like a train in the pocket. OMG!!!! ;-D

Comments about Roto Grip Roto Grip Mutant Cell:

194 average. F ing right doggy. This baby will rock your socks off. If you suck like I do get this ball. You will instantly score 20-25 better. Thanks Roto Grip!

Comments about Roto Grip Roto Grip Mutant Cell:

Had this ball drilled to hook down the lane and it is proving to be an all around great ball. I just started bowling with co-workers at lunch time once a week and this ball is helping me a ton. [...] After bowling with bowling alley balls I had to start all over again learning to bowl with a fingertip grip. Overall great experience with product and service.

Comments about Roto Grip Roto Grip Mutant Cell:

Bought it and couldnt control it in league but went to a tourny and shot 724 and got 2nd place. Its a monster!!!!!!!!!!

Comments about Roto Grip Roto Grip Mutant Cell:

OMG this is one of the best balls ever. I can hit any mark and it would strike no matter what!

Comments about Roto Grip Roto Grip Mutant Cell:

The Mutant Cell is the strongest of the line to date. This ball has about 3-5 more boards hook than the original cell. This ball has a great move in the mid lane and a continuous strong back end. I had mine drilled with the pin next to the fingers with the mass bias to the right of the thumb and a weight hole.

This is a great ball for medium to heavy oil.

This is the first ball I've had that people are coming to my lane and taking it to use during league play.

This ball plays best for me if there is some oil in the heads to get through the front of the lane.

Comments about Roto Grip Roto Grip Mutant Cell:

I received my ball yesterday and had it drilled and rolled a couple games with it. I was so impressed with the motion, I couldn't keep a smile off my face. A good number of people stopped and watched me roll the ball, then had a lot of people asking what I was throwing and wanted to see my layout.

The ball is very clean on the front, and makes a very predictable move to the pocket at the break point. I could miss 2-3 boards and the ball recovered really well. I tried moving left, then left some more, and was on 15 from the left with my feet, throwing 15 on right, out to 3-5 on the right, and the ball just read the pocket flawlessly. I am a tweener, not a cranker, and I have never been able to throw that line.

I moved right, standing at the center dot, throwing straight up 7 and the ball still made a predictable move to the pocket.

Needless to say, my local pro shop owner booked a few sales of that ball yesterday!

Comments about Roto Grip Roto Grip Mutant Cell:

I got 22 strikes my first series without any practice games. I had been in the longest slump (2 months) of my career. This ball is truly "Hook In a Box" and makes the competition (Virtual Gravity) look sick. I am a stroker that averages only 203 but feel I could bowl no worse that 650 with this awesome ball. I left only one ten pin all night. The Mutant Cell hits like a train!

Comments about Roto Grip Roto Grip Mutant Cell:

i am a league bowler with a 99 average and i bowled with this ball tonight and bowled 3 150's in a row this ball has great reaction on the backend and revs up verry quick i would reccomend this ball to anyone

Comments about Roto Grip Roto Grip Mutant Cell:

Amazing Ball..I got it from our local pro shop on thursday, threw 3 games with it...loved it..was learning it. On saturday I threw a 300 with it 753 set. On monday threw another 300 with it 715 set. I am a league bowler, bowl 3 times a week, average around 215.
Ive never had a more amazing ball, everyone must have this in there bag!

Comments about Roto Grip Roto Grip Mutant Cell:

Love the reaction on how clean the ball is through the fronts and how strong in the backends. The ball does rev up fast and good move in the mid lane. I really like the fancy blend of colors.
