Be careful!
First off, I LOVE(d) this ash catcher. It works perfectly and really elevates the experience. However, my first time cleaning it, the stem slipped and shattered in the sink. So I bought a new one. I've had it for a few months and I truly used it every time I smoked. I ordered the 3-pack filter replacements as soon as I saw them available. Unfortunately, my cat knocked the ash catcher off my desk and again, the stem shattered (nothing else broken). The filters arrived today but I cannot justify buying a 3rd ash catcher just to replace the stem. Here's hoping they offer it as a stand alone item soon!
