Bests & Worsts Reviews from Amazon

I'm a drummer, have been for over 50 years. Last year I was diagnosed with mild osteo-arthritis, uncomfortable enough to effect my playing and cause me to do something about it, like exercise. I heard about this product and the reviews were spotty but I thought I'd take a chance since some users claimed that use of this contraption helped them with their arthritis and strength issues. It's easy enough to use but there is one gaping flaw in the system. The stretchy bands used will snap after a couple of uses. I've already gone through 4 of them, I have two left, which means I'll be buying these bands forever just to keep using this thing. I'd like to return it for a full refund. I'm not going to spend my life re-buying bands no matter how cheap they are. The people that designed this thing are onto something really good but they cheaped out. Replace those insipid bands with some industrial strength bands or strong springs wrapped in nylon for flexibility. Those should last a user a long time, probably cost a little more on the outset but cost much less over the long haul. DO NOT BUY THIS PRODUCT UNTIL THEY IMPROVE THE BANDS. YOU'LL BE WASTING YOUR TIME AND $$.
