Product review (1 stars): Horrible. Ridiculously horrible.
Worst purchase ever.  Literally I curse this drain cover every day.

It covers the garbage disposal drain very well. Too well in fact.  EVERYTHING sits on top of it.  So I have to shove everything down manually.  It's ridiculous.  Even the smallest bits of food get stuck on top of it and clog up the sink.  So I have to reach my hand down there to shove stuff down.  And it's not just a one time push, it takes several attempts.

The plastic is too hard so it doesn't flex to let anything down the drain.  I even cut it to make the hole a little bigger but all food still sits on top.

So if you want a disposal drain cover that doesn't let anything down the drain.  Buy this.  If you are SUPER green and want something to force you to compost even the smallest bit of food. Buy this.  If you want to swear at a $3 piece of plastic daily.  But this.

But if you want most things to go down into your disposal so it can do it's job. Look elsewhere.

By the way, my wife said "Really?  You're making time to write a review about that stupid cheap drain cover?".  Yes.  If I save just one person from the mental aggravation of this purchase I will have lived a meaningful life.
