I use this with an arizer desktop vape. It works with the default bag mouthpiece despite the slush cup being 14mm and the vape bag mouthpiece 10mm. Very little resistance when drawing from the bag and you get a nice cloud buildup in the chamber after two draw which you can rip right after by removing the bag.

The bowl gets too hot to touch it needs a Handle...bad design you need a pair of forceps to touch the bowl...

Wow. This is a fantastic little pipe. At first glance after unpacking, I maybe thought it seemed small, but within seconds I filled it up, packed it up , and ripped away! So ****** smooth!!! I was looking for something that stacks and didn't **** me every time. You have a ton of control with this pipe. Primarily a flower user, I found that the water level is best 1/4in below the GRAV logo. For dabs I could see using less water, or if you're just really trying to blow your head off. Since I'm an over the top kinda guy I (***DON'T TRY THIS AT HOME*** i'm sure neither GRAV, nor 420science would endorse this practice) tried filling it up with a ton of water, tipping it on it's side and hitting it through the bubbler attachment from my helix-multi. It was a ****** huge hit and really only worth doing maybe once... ...Went to the moon, tho. Best little pipe I've hit in maybe ever. Completely worth the price. Shipping was timely. Will be back!

Good smoke, bowl is a one hitter, challenging to clean lower section, but overall, I like it.
