Has anyone had a problem with theres? I bought tank new on tuesday, primed the coils up like usual till they were good and saturated and after 2 days the .25 dual has burnt out..threw the .5 dual in thursday an now im back to burnt taste again on the .5..70watts was on the .25 and have been runnin the .5 at 65..anything longer then maybe 2 seconds puffing an im being gagged like a donkey..laat coil i have left is the ni one so need to know if its me or a bad batch n tough luck for the coils i got or others having similar problems as most reviews ive read usually end up almost a month per coil
