Product review (5 stars): Just like new!
I paid 1/3 as much as they wanted on the manufacture's site for this and it worked great.  It was a little different from the original on my Amana range, but aside from a little slight squeezing to tuck it into the hole, the brackets lined up just fine.  I saved at least $100 doing this myself and it was so easy.

I just had a couple tiny problems.
1. The convection fan on my oven made it hard to see the screws to take it out.  A a quick google on YouTube showed me I just needed to duck down a little bit more to see it under there.  Duh!  It was so easy!
2.  IMPORTANT: Unplug the oven, or turn off the breaker - I didn't, and it fried the lead wire when it touched the metal, and I had to replace the wire too. :(

Otherwise, just unscrew two screws, pull the little metal connectors off, connect it to the new one and screw it back in.  Just like new!
