PHX Glass

this btw is the god of all bongs.....my friend had one he bought for $450
triple, self leveling diffused, chambers; ultra filtration; no rubber sealing anywhere, thick ass glass, suprisingly light, the best bong iv ever seen or hit....its a trip to see in action, and its is hard to figure out what is going on even in person up close....it ended up getting stolen and broken in the PROCESS of the attempted robbery, dumb ass criminals

Yeah these and roors are good stuff. The roor is cheaper. But yeah the reason its so light is because its labratory grade glass and process. The no rubber seal is also the main key to these suckers and the straight chamber makes for quick and easy filling and clearing.

Roor is german made , phx I have no clue. Ive seen both. The roor is great though for half the price.

yeah a couple of friends of mine have roors also, they are def a great bong for a better price i must say...but the $ for this bong was not regretable....fill the top up with ice and ur ready for fun!
and i beleive phx is out of berkley btw
