No me gusta que falle demasiado y no vibra?Does the job for the price I just wish it was a little bit more powerful. After each use you need to charge it but that’s OK.I use it when I get a Sinus headache,I massage right on the pressure poin.I bought it a month ago. It was worked fine. I have charged it every time it needed. The last time it “died”, I went to plug it in, and the light came on like usual. I kept it on the charger for the same amount of time I always have, and it wouldn’t turn back on at all, but even after unplugging, the light continued to stay on but wouldn’t actually turn on.I been using this on my sore muscles. Does not seem very powerful. I am wondering if this might possibly not be what it was meant for??? ;-}Don’t waste your time. Cheap ain’t always good !! The product came in a plastic bag inside the package box! No charger! No nothing! Also it was DIRTY like it was used before hand or something! Tried to turn it on but it wouldn’t come on. I figured i could use my old charger, but after sitting on the charger for hours it STILL did not work! Since it was only like 9 dollars or so i don’t care to return it. Just wanted to warn yall ?It’s ok but it’s definitely not the bestIt's hard to turn on sometimes but for the price, it's pretty good.
