Bests & Worsts Reviews from Amazon

Having recently suffered a wrist and elbow injury, I bought this set to work on gradually building my wrist and grip strength back up to that of an average adult male. I was shocked and mildly pleased to find out that my injuries have somehow given me near herculean strength, as the adjustable grip strengthener pictured above shattered NEARLY INSTANTLY in my hand upon first use. The cheap plastic and loose metal parts were no match for my near 2000 psi of grip force that I have calculated based on my experience with this item and it's 60kg resistance limit. I will be returning it (and the other items) and looking at other options to train my superhuman finger forces. I still am unable to do more than 3 pull-ups so my powers must be limited to my lower arms. I have yet to pick out a super hero name but I am thinking something along the lines of "Mr. Hands."
