Great. Hits smoothly, and fits perfectly with my glycerine coil and my straight tube.
This is one of the best pieces i have ever had!
This is a great start to an awesome modular water pipe! I have this STAX turbine base with a standard GRAV 90 degree ash catcher, STAX tree perc in the middle and the STAX standard ice catcher mouthpiece. The tree perc ended up breaking (my own fault) but only the perc within that section... the tube of the STAX is made VERY strong/thick. Good thing about a STAX is that I still have the base and mouthpiece so I still have a fully functioning water pipe. I'll have to buy another perc, eventually (they aint too cheap.) I do highly recommend to anyone who likes modular and customizable things.
