What a piece of junk. You plug it in and it works for about 30 seconds, overheats, and fails to continue to work. Don't waste your money on this. Unfortunately I waited to long to return it and now Amazon won't refund my money. My bad, I guess! Don't make the same mistake I did.
I love shiatsu massagers- I have a neck and back one and have been looking for a reasonable priced handheld one, I bought this one- like the others said- it stops working after about 1 minute! I'd let it charge- even though it does not need to charge- it plugs in constantly while you use it- and I tried it again- same thing. Exchanged it for another one- same exact problem! Has anyone gotten one that actually works for longer than 1 minute past the medium setting since you can't feel anything on the lowest ..
I got this as a gift for someone else, but I thought I would try it out first and I was completely apalled! It says it's a "Rolling Shiatsu" massage...but I couldn't feel anything rolling or shiatsu about it. I've had better massages with those little plastic massagers that cost like $5. Plus, the higher intensity you went...the worse it got! Don't waste your money on this!
