Check out my new bong I just purchased....its the absolute best thing I have ever toked! Beats any PHX and Roor I have tried easily IMO. Each perc chamber has 4 diffuser tubes...for a total of 8. It was custom made for me by Brandon at KIND CREATIONS in Colorado, he did a fantastic job! Approx 26", 5mm, w/ double bubble base/ diffuser stem and ice notches. It also has a double chamber ashcatcher with diffuser stem aswell. He even went the extra mile to sand blast my nickname into it! Tell me what you guys think!!!
