@Gr1mSag3 , the fat boy glass is an extra glass that can be bought. The RBA deck is larger than stock coils, so reduces the capacity of the tank, the fat boy addresses that, if used with stock coils it increases the capacity of the tank. If your Cleito has just started to leak it could be to do with the warm weather we are having at the moment. When warm, juice gets a bit thinner, I've had a little weeping the last two days, but nothing serious.
Thanks, I think I eliminated user error when priming as a potential source of the problem with either cleito tbh.Remember to start at a much lower wattage say 25watt for the first 5 /10 min to let the coil settle in.
