I broke my first one after tripping and catching my whole body weight (180 lbs) on the marble surrounding of my tub with my Grav straight base 18" water pipe and only the arm broke on the ash catcher and nothing was wrong with my water pipe at all (thick glass). My only complaint is that I bought another one and the rings on the inside of the ash catcher are not as thick as the other one and thus I feel it has less filtering ability. I really wish the 2nd one I bought looked just like the first one. However, it seems to function similarly. Just beware that if you break it, your replacement may look slightly different.
