This cools the vapor down far more than any other stem I have. I'm using it mainly with a Vong Ti tip and an Armored Cap from Dynavap. The fact it's able to cool down the super hot vapor from the armored cap is impressive. Bong with a WPA is still smoother of course, but that's to be expected. Would recommend for sure!

I’m using this with a titanium adapter as a mouthpiece for a Vapman. I’ve used GC’s stems in the past for their intended purpose and liked them a lot. I especially liked that this stem had no carb hole; before I bought it I’d wrapped the hole on an older model with hemp twine, but this works better.

Just like everything I’ve ordered from here, I expected these stems to perform well — and they do. They’re thick and heavy, and cool really efficiently. There’s tons of dimples to cool the vapor and with the extra thick walls, there’s little to no heat transfer to my hand, and I love that there’s no carb. I’ve tried with ss and ti, and both work well; equally but differently. I’m really rough on glass and shouldn’t be trusted with it, so I ordered 2 right off the bat; even being in my possession, they’re both still intact. I’ve probably jinxed it now, but these are strong!

Awesome product gonna have to buy another one soon, along with some dosing caps.
