I have a 3-ball Storm Streamline that's about three years old. It's held up very well except for one zipper on the front pocket. It's off-track and the pull handle is bent pretty badly from trying to get it back on track. The other works, and they're both off to the side, so I can still get into the pocket.
I really like the fact that the ball cups are deep. A few others around here have Brunswick and Ebonite bags and they complain that the ball cups are pretty shallow and allow a good bit of movement.
The bag has plenty of room for accessories, though I wish I had the newer one with two smaller pockets instead of one long one, as little things tend to slide all over the place and get in the way of putting my shoes away.
