For those of you looking to use the T3S coils in your PT for a tighter draw...You must use the insulator(gasket) from the PT to use them otherwise they will leak. The T3S uses a bigger post on the coil than the PT but the posts are removable. all you do is unscrew the tank from the base while it is on your battery(or off) and wiggle back and forth until it comes off. You can now remove your flavor wicks(the ones on top of coil) but Do not remove the ones inside the coil. You can actually dry burn/clean your coils w/o having to waste money on buying new ones every time they taste burnt. All you do is run under warm water and dry burn it until the coil is bright red. Repeat until it looks bright white and coil has no build up on it! As for the flavor wicks...pinch in fingers and run water over your fingers while rolling back and forth. All done...Put your coil(s) back together and vape on!!! It may taste a little funny at first if you don't let the wicks dry completely but even if you do not it will taste fine after a few hits or so. Enjoy and I hope this was helpful!
