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?
My house had the cheapest garbage disposal which I quickly broke. When I went to replace it, I found that replacing them is incredibly easy and the mid-tier model (about $120) said it could handle small beef bones and peach pits. I’ve been very happy with that, and all my food waste goes in. I don’t have a lot of room for compost, but the city purports to be generating electricity from the sewage, so I hope it isn’t wasted. It also means that my trash doesn’t smell, which is nice.
