wat 27 ohm 0.38. im already buy 4 month ago i did not expect too early that puma becomes worse..over taxing the mod ?
what ohms is the coil what wattage are u running mate
I didn't know what a puma mod was, so I googled it...
it appears that there's a whole load of people with board issues, there's people commenting under youtube videos saying the same thing as you too.
I know that's no help though, sorry..
if you've only just bought it I would just take it back and get something else, it really doesn't look like a good mod.
