Hey all it is a PHX which is kinda a roor knock off sense it is not a roor but phx is by far number two in the glass world right now... ass for how it hits fucking amazing... smoothest hit i have ever had... you would think going through four filtrations (i have the option to go five filtrations but i am not to keen on my final bubbler (not pictured: it seems to burn the ganga better in the roor bowl) it would be sort of hard to hit... but NOT AT ALL!!!! IT must build up its own power during the hit... you barely need to put fire to the bowl (one sec max even if the bowl is packed...) if you start out really slow and let the ashcatcher and the precooler condense the smoke and then let the final defuser and perculator do there jobs you can easily take down a half a gram three quaters of a gram down in one hit... not wasted smoke either the bong filters so much and condenses so much that once the smoke pass through the ice it is like breathing cold air... (when properly filled the bong reachs a temperature of 48 degrees) How stoned you get off of this bong should be experienced by all.. if you have the means buy a PHX from you local head shop you will not regret it... oh yeah its name id TOWER OF POWER!!!!! lol
