Vaporents

Actually I meant that getting an WPA and attach this bubbler to the WPA, so you can skip cleaning the CU itself. Also, if no water works well for you I guess it's better, saves more flavor. Anyway yeah that's a nice solution :)

My vape is a bit different. It's on demand, so it heats the herb only when I hit it basically, so usually I let it sit a few mins between hits (no specific reason, just how I like to hit it). When I do hit it back to back, this stem works great and the vapor comes out nice and cool. When I'm out I have a small dimpled glass stem which although cool it down, I admit that not 100% (I had longer one that was also portable that did cool, but it broke and I didn't bother to repurchase as most of my usage is indoor anyways). BTW, You can easily attach a bubbler like yours instead the stem as long it has a 18mm (19/26) male connector.
