It's ok to use on yourself but honestly not amazing. It's too difficult to apply the necessary force to properly massage your own back and doesn't feel great on legs or arms. It is best used by somebody else on you if you plan on using it. That being said, it's so cheap for what it does that even if it's mediocre for self use it still might be worth it. Also functions as a vibrator with plausible deniability lol.
