The band is very good because it has the damper always at hand. I have to complain about, however with my copy that I had to edit the recess for the button only! In the original state of the ring has the button with all batteries (Original Joyetech) böockiert the current steam output had almost destroyed the filament, I had filed out half a millimeter of the rounding, it worked! Therefore, I can unfortunately only awarded three stars!
