I love them! Much better than the toxic plastic crap from the pharmacy that was always itching me! The washing part is a little bit annoying but you will get used to it.

Ex Output:
positive

Ex Input:
it worked great for a few months and then it suddenly stopped charging. it repeatedly bumps against the dock but never begins charging. the battery is now dead and it doesnt work anymore.

Ex Output:
negative

Ex Input:
Literally came broken so I was not able to put the battery even into it. It comes with a blue battery that is not a normal battery. And It is also all in Chinese and hard to understand the few English sentences in the manual. Don't buy this.

negative
