Been using one of these in my favorite glass bowl for the last six months and I can say I really recommend this little dude, as expensive as they seem the one I have is good as new thousands of bowls later, check these out! I need to get some more for my other pipes so they’re not as neglected, never been a mesh filter fan but I used to use glass jacks those were nice but this doesn’t fall out when it helps you kick the bowl the way the jacks do:
“How can i tell if a Smojo will fit my pipe before i buy it?
The 2 things to check are the size of the hole and the clearance beneath the hole. If you have a set of drill bits, if the 1/8" drill bit slides through the hole at the bottom of your pipe to a depth of 3/8", Smojo should fit. If the 1/8" drill bit will not slide through the hole there is little hope that Smojo will fit. Another test is to take several paperclips (normal not jumbo size) , straighten them out, and see how many can fit in through the hole at the same time, 4 is marginal, 5 or more and Smojo should fit.”
