Product review (4 stars): The good: This one is thinner
The good:  This one is thinner, floppier rubber than my  previous ones so food is more likely to fall through it without me manually forcing it through.  If it fit my sink, I'd buy this one every time.

The bad:  This is the wrong size for my sink.  I listened to people here who said there is just one standard sink hole size but that's not true.  I forced this in anyway, with some bends, because I hate the stiff one that's in there now and I hate how gross these things get.  So I'll use this for a while and then toss it and probably go back to the correct (around 3") size.  I throw them in the dishwasher all the time, too, but still they get gross and won't come clean.
