I've had a Storm 4 ball roller for approx. 4 years. I had to replace one wheel and a broken handle. Called Storm each time and had the replacement parts within 5 days. (3 days on wheel and 5 days on handle) There service is excellent on things like this. If only they had the same type service in regards to their balls.............
Look the frames over good. Even though K & R makes most of the frames, they used to make them according to a companys specifications. Don't know if that is still the case today or not, but would suspect it is. I know that Storm, Brunswick, Ebonite, and K & R have excellent frames and ditto for the material on the bags. However, I've seen some cheap looking Columbia's (light frames and cheap material) as recent as last year. Don't know if that is still the case today or not. Thats why I said look them over good. You can't go wrong with Brunswick, Ebonite, Storm and K & R.
