Product review (5 stars): GE product for just a few dollars - worked out well
No problems. They fit well enough and replaced the rusty chrome ones the landlady had left here. Can't see the dirt, which reduces stress about cleaning them. Couldn't believe how inexpensive they were compared to the ones in the store.

The plastic bags they were each packed in did say they were a GE product as well.

One small issue people might care about - the small ones don't quite stay level unless a pot is on them. This is a GE stove so I'm not sure why the fit isn't perfect. Doesn't bother me now that I'm used to it but it's a small annoyance that some people may want to know about.
