Great little squonker I paired this up with the drop rda threw on a single n80 fused Clapton , ramp up time is fine and hits pretty decent. It’s made for a single coil but the box doesn’t leak and for a single battery (20700) regulated running a single coil it’s great doesn’t get hot. If your looking for high power this isn’t the one but if your looking for decent cloud and a good first time squonk that doesn’t break the bank. Get this !!
