I know right? Things like this make me not want to ever order anything that is a kanger product.
Although I don't know the entire history of kanger, I've heard a lot of vendors stopped using them. I suppose they probably copy your design because they think it'll get them more business. The button doesn't mean anything if they still aren't making a good quality regulated battery.
Funny thing is, after talking to another vendor which swears up and down he buys from the same factory you do, yet his bats don't last as long as bloog or volt bats, I'm kinda thinking he's using kanger. A few days ago I contacted them and asked about these 808 bats and they told me "we can make rubberized finish to look just like bloog" LOL - They really want to copy you, and apparently other vendors do too. Competition is fine, but not when a vendor has to lie about it to customers and then they find out performance/life is NOT the same.
