Query: Cheap construction

There's hardly anything "automatic" about this can crusher. It has a cheap piece of plastic that forms a feeding bin on top. However, for anything other than occasionally crushing a can or two per month, this thing just doesn't hold up. The bin isn't "automatic" as cans often get stuck instead of feeding the crusher. So while it seems like a good idea in a single picture viewed on a web site, in practice it doesn't really work well enough to be used regularly.
