Product review (2 stars): Three little ones fit, the large one is slightly off.
I'm very disappointed.  The three smaller ones fit, the larger one does not.  It doesn't seat correctly.  It looks as though it is the same size as the existing one, but when it is in, one side lifts about a quarter inch from the stove top.  I was going to send them back, but they were going to hit me with around $9 shipping charge, plus I'd have to box it up and truck it down to the UPS store.  The stove is a 24" Hotpoint that is probably over 20 years old and I can't find the model number, so I took a chance that it would fit. But for the cost of the shipping, I can go to Walmart and hopefully find a thinner one that fits right.  The large burner is the one I use every day, and the existing drip pan is uncleanable.
