I have used small attys for so long and now i am looking to try a larger one, question is for anyone who has tried the SINGLE COIL IGO. I realize it only cost $8.00 (good test price) but does she leak and does the top cap stay in place fairly well, build quality looks decent for eight dollars. May try a dual coil down the road but right now i rock 24mg and on rare occasions I'll hit the 36mg juice. Thank you ALL for the help!
