The stem is to small for the heat chamber. It wont seal and doesn't work.Great idea to bad it doesn't work
This product was great until it wasn't. I've had it about 1-2 months. After daily use and occasional cleaning with warm soapy water and a pipe cleaner brush (about once weekly. Also not an easy task) , one of the inner glass tubes appears to have broken. I noticed when the water would drain out and make a sizzling sound when it touched the heating element of the Arizer. You can still use it without water but then its just a normal stem without the cooling bubbler. Bummer!
Used this for less than a week and it is already broken (center piece broke off from pipe itself). It is great when it works, but that's only if you can somehow keep this thing from breaking. The holes drilled seem to significantly weaken the glass
excellent product...would buy again....Oh wait I did buy it again as a backup
Would like the stem to fit a little more snugly but other than that it gives a nice cool draw.
