I've had mine for ... well... simply ages now! -- and it's never given a hint of trouble. It does just as it should (coupled up with the associated little USB lead) and has now charged quite a few different batteries umpteen times, all without a hint of anything getting dangerously hot!
This is one area I think one should never skimp, as the results of an exploding battery are usually quite horrendous.
I would posit that Ecigwiz have taken a lot of care never to sell dodgy USB battery charging devices as they know full well what the dangers are, -- so good on them for that!

It is a tidy and solid adaptor and provides the versatility of being able to recharge from any wall socket rather than searching for a usb connection.
