My berserker mini arrived today, very happy with it overall! It's a lovely sleek tank, build quality is superb. Only been vaping on it for a little while but so far for flavour I would rate it about same as the 22mm Siren V2 and slightly worse than the sxk doggystyle which is my current favourite. Whats up with 2 the supplied coils, anyone know what spec they are? Neither worked for me unfortunately, 1st just snapped when I put it in and tried to dry burn it, think I might have had it around 20w accidentally though . 2nd doesn't seem to be detected properly, getting errors on my mod saying atomizer low? Anyway I put a kanthal 1ohm coil in, same as it what is in most of my other mtl tanks at the moment. It seems to be better to run it on a lower wattage than other tanks, for example I have same coil in sxk doggy with same juice and I have that at 11w whereas the berserker seems about the same at 8w. Only difference I can think of is there's less cotton needed for wicking in the berserker.
