I picked up this gem about two months ago. It's pretty much been my to go piece every since. This one is a variant of the standard Monsoon that Chameleon Glass makes. If ya haven't checked out their glass, it's worth a glance. I've smoke everything but oil on it and it works amazingly, but it will get pretty dirty in a weeks time if you're dabbing off it regularly. You add water to the middle chamber by filling it from either end. It's completely spill proof and it actually works. It's also easy to clean the water out, just blow down the tube and the water pushes into the bowl area for an easy dump. Any other Chameleon fans out there?
