Could be good, but.
Had it for 2 days, and zero results. It does not come with even a postage stamp size piece of instruction. I charged it and fiddled with the remote, and it did not work. I contacted the seller, who is apparently in China, and does not understand English! After 3 ridiculous replies, none of which had any resemblance to my question, I was told &#34;Follow the instructions&#34;! In my first email, I mentioned &#34;No instructions&#34;. I was also told &#34;Increase the power, after I had told them &#34;It will not turn on&#34;! It seems like a nice piece of work, and I badly needed it for my severe neck pain, but without a seller to back it up, and no instructions, plus a non working unit, I gave up and sent it back.
