I don't know if you bought one already but I snagged one from my local Sears and it works great! It's rather large but on the lower settings the flame is perfect, relatively cheap at $30 too
I own that piece and use it with my Lotus Vaporizer, it's great! Slits are pretty big so the bubbles aren't quite as small, keeps a good amount of the flavor
Had some fun with my 18-14mm adapter and a friend's LSV... Flipped the adapter upside-down and it fit over the top of the WPA. Really great for micro-packs!
After showing my Lotus to all my combustion friends I managed to get a whopping 4 of them to buy one of their own! Now they fuck combustion and refuse to smoke after being adamantly against vaporizers because they "don't work"
it's not as much that it's bad it's more of it being cheaper/less sturdy. I own american and chinese glass and I'll be honest that my 30$ chinese glass bubbler is my favorite over my more expensive american made pieces
The plate on my lotus seemed to develop a bit of a crack.. and now it is giving off a powerful wood smell and offgasses when I torch it without the bowl attached. I don't feel safe using it until I can replace the cover so I suppose I'm back to combustion now :/
