Product review (3 stars): Missing critical groove
I bought these a while back as spares and recently installed them in my GE electric stove.  The packaging says GE on it.  They fit fine in the hole, but, if you look at the picture, there is a groove for your burner base to fit into allowing the burner to lie flat.

These replacement bowls do NOT have this groove. Which means the burners do not lie flat.  They almost do, so they look OK, but you just know that when you put a heavy pot on them, something has got to be stressed.

I'm off to look for some with actual grooves to accommodate my burners as I don't want these on my stove for long!

Update:  I found the one with the groove:  http://www.amazon.com/gp/product/B001TH7GZU?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00 This is a link and I hope the link takes.  If not, search stanco 4 pack ge/hotpoint electric range chrome reflector bowls with locking notch.  This allows my burners to lie flat like they are supposed to.

I hope that my review will prompt the company.  In fairness, I bought these about a year ago.  Maybe the product has changed to match the picture?  Either way, I doubt these are actually GE replacement parts since they don't match what I replaced.
