I bought this not expecting too much to be honest, but I was really impressed with this, gives a great draw and best of all you can open and close the carb hole, this performs much better than the factory dyna_vaps.
Sit nice in the hand, not too heavy but feels really solid, a little heavier than a omi and a decent price, can’t think of any bad points,
I mostly bought this because it looked like a lightsaber handle, but it's actually awesome! It's nicely balanced in my hand and the fatter body and grooves make it easier to spin than my standard stems. The adjustable airflow works brilliantly, Omni feature at M pricing most importantly, it hits extremely well - better than my Woody, M,Omni and PhatPiggie stems! The 'spiral airflow' thing I thought looked gimmicky but somethings happening in there I guess. I should have maybe waited longer after testing to write this.
Someone needs to make a 510 drip tip that looks like a lightsaber blade.
