Sharper Image® Powerboost Move® Deep Tissue Portable Percussion Massage Gun, 4 Attachments, Rechargeable

I purchased a similar device and right out of the box it would cut off if you put any amount of pressure. Sharper is was recommended by a friend so I purchased it and the vibration is amazing, if I need to add a little pressure it still keeps working and the 20 minute auto shutoff keeps me from over stimulating my muscles but gives just enough time to penetrate sore muscles and relax them. I suffer from leg and foot cramps in the middle of the night and this helps quickly. I love that it doesn't take forever to charge and holds its charge for days with daily use and as long as it's not used it's still charged when I have to use it again.

This massager came recommended by a fellow worker. It has a lot of power and really helps.
