No kidding! I usually hit it once, exhale thru my nose while taking a second and hit the 10 sec. or so cut off. But I'm usually good. Need more, just double tap the button and keep going. I believe the cut off is based on the current draw so a higher resistance atty/cart will go longer than a low resistance atty/carto.
Supplier shipped my replacement so I'm hoping it's the V2 with the EGO threads and one piece head- maybe try a Kanger or something someday.
Get the Kanger Protank! The T3 and MT3 both end up with the knurled bases below the center cone line. So if you twist it on too tight and can't get a hold of the base when trying to get the Kanger off, you'll only unscrew the tank portion and end up with liquid on your slacks while your co-workers all point and laugh TWICE!!
I just tighten them enough to get the connection and not more.
