Was dubious about this massage gun before I purchased it but was pleasantly surprised to find that it works great. Very sturdy, well built. Came with a usb lead to plug into an wall adapter (it doens't come with the adapter) made sure to fully charge it before I used it. Husband suffers from sciatica nerve, this massage gun on level 3 was able to glide over his hip areas and relax him to the point that he had no pain whilst he slept. Great on the soles of your feet too. Highly recommend!
