purchased this bowl because i read that it worked with my steamulation HMD.. apparently it's the only bowl i have that works with it.. that HMD is small and this is a fairly small bowl that's best used for solo smoking. doesn't seem to have the issue my other silicone bowl had of overheating. i think my other is aluminum base instead of crystal though. design cuts down on molasses drip too if you don't have a catcher.
