Product review (4 stars): Fits Jenn Aire double ovens - barely.
Purchased for a replacement for my Jenn Aire double oven unit.  I know it fits other makes/models as well.  Package came promptly and was pack nicely to prevent any damage.  Installation was simple and so far the element is working great. It was slightly smaller than the element I took out, but it did somewhat fit my application.
Pros:
Good price
Fits Jenn Aire double ovens
Easy installation

Cons:
None so far
Tight fit for the Jenn Aire double units

Only difficulty I had was the installation, but that's because the screws that held it in was somewhat rusty and it was a tight fit with the brackets that holds it into place.  But I finally got it in and it seems to be working fine.  I'll update this post in the coming months on reliability. So far after three months of use, no issues.
