It has decent power. Any deep pressure will stop the vibrations, so it's pretty useless for deep tissue. The heating element doesn't get better the luke warm, not enough to penetrate the skin and do any real good. The attachments are nice and plentiful. The on/off switches are sensitive and in a lousy spot if you actually grasp the handle to work out your kinks and soreness, your hand will constantly hit the switch and accidentally turn it off.
