Just have to say one thing. Buy some Sony vtc3,4,5, or 6 and be done with it. Which ever ones you can find. If you get efest and they say its vtc3s be sure to look at the battery and find that long azz vtc number somewhere under that red shrink wrap. Same goes for the eh battery. A lot of fakes going around. Be safe guys. And most of all smart. That old phrase has been around for ever for a reason, if its to good to be true then it is.
