Product review (4 stars): Great tool at a low price
I needed something for a primary purpose: pushing things through the disposal's splash guard. I don't typically look for the cheapest thing out there, but look for the best thing for the job. Others cost more, but would hardly bankrupt anybody. Yet this one does the job and more. It sits in the opening in a way that won't damage the splash guard below. It can be left so that the bottom ring is flush with the flange, so water drains and most particles will wash down the drain, yet items won't fall in. It's practical for pushing larger items, can be pushed down to use as a stopper, and comes with multiple rings so appropriately sized ones can be used.

Setting it up merely required putting on the rings. The instructions hinted that their tips would make it easier, giving me the impression that it would be harder than I might have hoped for without instructions. Yet it was easy enough that no instructions or tricks were really needed. The rings did all come pressed together and at first glance they seemed to have multiple grooves, but once I pulled them apart from each other, the rest was simple.

I had initially considered buying this together with a few alternatives so I could see which one I liked best. Then I decided that if I didn't like this one, it was cheap enough that I could always buy something else if it didn't work out. I'm glad that I got this first. It's everything I need.
