Product review (3 stars): Nothing too terrible or drastic
The larger drip pans are a bit ill-fitted. Nothing too terrible or drastic, but there is a bit of a lip on one side where it doesn't quite fit in as smoothly as it should.  Once you put the burner in it sits firm and doesn't move around much. Honestly, I bought the Stanco chrome drip pans because the Whirlpool brand was out of stock and I needed them ASAP, but if you are able, get the Whirlpool. If you are renting and you need something fast and don't really mind if it's not perfect, then these will do just fine. I think these are just a little bit cheaper than the Whirlpool brand.
