Product review (5 stars): Waste King 1025 Sink Stopper and Splash guard for EZ Mount disposer #B000HE5DNI
This review is for the stopper and not the actual waste king disposal (disposer works great though and easy install for our plumber). We've had the disposer for a few years now and for some reason the old rubber one kind of stretched with washing it in dishwasher, I guess.  Anyway, when I would push food down, the splash guard sometimes would fall in the hole. Bought the new one and although my hole was slightly over 3", the guard I received was 3" and I carefully worked it down, voila, fits perfectly and doesn't fall in when I push food down.  I'm anticipating that it too may stretch somewhat with use, so I will order another one to keep on hand when I order some other item from Amazon.  I'm wondering how much research others did when looking for a splash guard as there seem to be so many complaints.  Have patience and just slowly work around the circle as you seat the guard in, it will fit!  Yes, would have preferred to buy just the splash guard and not the stopper as I already had one.

I wish Amazon would separate their reviews for actual guards or disposers, not bunch them in altogether.  This goes for other companies also.  Case in point are the TV's, looking at reviews I would find all different models for same brand in one place. Time consuming when one is trying to get an accurate review.
