Product review (5 stars): Good product, good seller
The product was shipped very quickly, and well-packaged for product integrity.  The element is in perfect condition, albeit with no instructions.  It is surprisingly easy to install.  (1) Unscrew as much as you need (don't forget the WD-40 in case the screws are aged).  (2) Pop the back, pop the contacts on old element, push contacts together on new element (note that the contacts may be at 45 degree angle compared to your old element).  (3)  Put back together. Give yourself time and don't yank anything, it should separate and come back together very easily if you have the proper angle.  (4) Let the new element heat and air for awhile, there is a slight chemically smell.

This is also a good opportunity to clean the oven and the space around the oven.
