When I was growing up, these seemed to be ubiquitous and I never liked them. They seemed overcomplicated for the purpose, and created a gross and smelly area under the sink that needed more cleaning.
I haven’t had one in years, as a simple sink mesh does the same job. But I don’t really know how other people are. Are under sink garbage disposals still common, and commonly actually used by people here?
The upgrade is so worth it. I got a 1hp one when I needed to replace the old one. I could probably send a whole rotisserie chicken down that thing without issue (other than destroying my plumbing anyways). I don’t deliberately send bones down it but it has happened and they don’t even slow it down.
