[Disclaimer: if you do not smoke out of a water pipe disregard this post]
Ive recently acquired a $20 tree perc ash catcher from my local smoke shop and I am so impressed with the outcome that I had to try to inspire other people to make the investment.
Do you like big rips? Does your downstem get too dirty? Have a tricky water pipe to clean? How high?
Anyways, if you answered yes to any of these questions, I guaranteeyou will see a significant difference when you decide to invest in your new glass extension. Also dont be afraid to buy bigger/smaller pieces because you can always buy adapter pieces as well that come really cheap (~$5).
There are a lot of good extension pieces that I had no idea existed for a while when I was smoking daily out of a bong. Lo and behold, they are cheap and can make me clean the bong less? Sounds like a deal to me lol
