Excellent unit and Ez to keep clean. I am a mighty man tho. Love em. I have owned 10 vapes and 3 of them Mighty with last 1 being the plus. Easy draw, EZ clean and seem like quality. Great battery life and fast charge. Puff-it-up is great. SB usually are. Had service repair on first 1 (went great). 2nd one they promised a future "service pack-replace batteries etc" but when inquired they stated we ended up not offering that service. Still love em but make sure it is not a future promise is all. Expensive but imagine I have saved that much in **** per unit since I use half as much as I did b4.
