I bought two of these for my double sink. I thought they would be great if they worked. Not only do they work, but they have exceeded every expectation. 
It’s a brilliant design which lets me stopper liquid in the sink or let it flow while also straining organic bits which I can then compost. (I don’t have a disposal). The rim of it is flush with the 
sink, making it easy to sponge remaining 
organic bits right into the strainer. Please thank whoever thought of this for me!
