I would be worried about the battery too. Buy right the first time - if it's gonna help you cut down/quit the stinkies then give yourself every chance and buy from a reputable vendor. I believe a popular starter kit is available from myepack here
Thanks for the info, I done some research and its made by kamry I already have a kamry k101 and its awesome the tank is a protank clone and apparently just as good for half the price I buy most my stuff from myepack good vendor gonna take a punt on it for £10 I let you know what its like
