I am licensed Licensed Massage Therapist in Hawaii and a lomilomi practitioner who "shares" with many recovering from serious injury, illness and surgery. I have Hypervolt, Theragun, Master Massage, Sharper Image Power Boost Pro equipment and a Class VI medical grade laser machine @ my office but I have 2 Gen II massagers @ home that I USE on myself almost daily. Easy to charge, easy to use, and does a very good job getting at spots difficult to reach with other models. Just enough percussion to dig in and release challenging areas.... GREAT handle length with just enough flex. I leave the acupuncture tip on mine and keep my 2 units charged up. I find I can get almost an hour of massage on high speed from a full charge. I also recommend the Purewave Gen II to my clients and at least a dozen have purchased for their home use too.
