Bought two of these on clearance sale. One worked fine out of the box. Nothing special. Pretty finicky. Very little latitude between no vape and scorch when using temp control. Second unit spit. Spit like an active volcano. Tried everything I could find on the net and both drop in coils. No change. Unusable tank. I am keeping it to try with the RBA. Noted quite a few mentions on net about spitting.
Can not recommend this tank. Obviously, from my experience, it's a crap shoot.
