Crafty(+) / Mighty / Boundless CF / CFX / Tera Glass Mouthpiece

Surprised by how much this helped!

Cooled down vapor much more then expected. No more coughing!

Mouthpiece CFX hack

I use these mouthpieces for the CFX Boundless hack. They don't fit perfectly but far exceed Boundless plastic mouthpiece.

Works well enough

Fits decently, though as said by others on here you have to fiddle with it a bit to get it to stay firmly in. A bit disappointed that it's already developed a chip/abrasion at the tip of the mouthpiece. I don't recall it having been dropped or bumped, but suppose that someone else could have done it so am hesitant to blame it on the product. Just know I have plenty of other glassware that HAS been through bumps and drops and remained undamaged. Didn't notice much of a taste difference compared to the stock plastic (makes sense since the majority of the unit is still plastic regardless). But it is nice to have a visual cue on when it's getting too dirty. Overall if your keen on glass and not clumsy this is a decent option for it's cost.

Fits perfectly in my Boundless CFX. Nice improvement in flavor, and helps slightly with cooling the vapor

I bought this for my Boundless CFX I got ~2 weeks ago. I'm verry happy with it. For me installing it with the silicone/rubber part (IDK exactly what material it is off the top of my head) with the thicker part facing down (so the thickest part of it is the deepest in the hole the original plastic mouthpiece goes in). I have it installed like that, and then just put the mouthpiece in by inserting it while twisting back and forth. It's a very snug fit. I don't feel any risk of it falling out at all and it rotates perfectly fine like the stock mouthpiece. My only minor gripe is I think it should be just a little bit longer. I understand having a glass piece made like this in what I'd imagine is rather low volume is expensive. But just a quarter of an inch longer would have made the difference. It does look a little silly IMO just because of how short it is but functionality wise it causes no issues and I have zero complaints.
