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?
I use mine all the time, much easier than dealing with a nasty sink strainer as I just spray down the sink into the disposal and run it. Also keeps the trash from smelling.
If it’s being smelly under the sink, it’s broken or not installed right. If it’s being smelly from the drain hole sink side then you’re not cleaning it from time to time (Which is as easy as dropping in some cleaner and running it every other month or so).
I’m actually looking to upgrade mine so it can handle some bones
