Review on Hypervolt Go 2 - Quiet Glide Technology Massage Gun For Sore Muscles & Stiffness Relief by Paul Ziegler

Bought this from another authorized retailer. Battery was dead in packaging, not a good sign. I charged it for over 2 hours, the charging light became green indicating it has a decent charge.more than 3 times it would start and just shut off. clearly a defective battery. I just wonder how many more defective units are out there.also, from the few moments it did work, its very hard to believe the stall force is 40lbs.
