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?
Using it regularly for a few seconds when food falls in means no clogged pipes, because it breaks food waste down to a size that is easily flushed down the pipes. If you wait until it gets clogged then you are doing it wrong.
