Comments about Brunswick Competitor Players 4 Ball Roller Blk/Stl:

Since I only recently received the bag, I can't state how durable it is, but it seems very well made. The design is excellent. You have completely separate two ball bags that you can carry in separately or you can take the top bag off and roll only the bottom half. This makes it nice to have a bag for synthetic and a bag for wood lane condition.

My only complaint is that both bags could have additional side pockets that would have allowed me to segregate my accessories in separate pockets. This is not too important because there is plenty of room in the storage compartments on the top and front of the bags.
