Product review (5 stars): FIVE STAR EASY!
I admit to being pretty handy, however this product is incredibly simple to install.
1) Pull oven away from wall (unplug while doing so)
2) Locate probe from inside oven and then remove panel on back of oven to expose back side of probe
3) Remove screw(s) that holds probe to back of oven.  I had to remove only one screw.  The screw was VERY accessible.
4) Remove probe and then unclip wire with a simple pull, no tool is necessary for this step
5) Install new probe in same spot that old one previously occupied and reclip wire
6) Reinstall screw(s)
7) Reinstall back panel
8) Plug in Oven and push back in place
9) Bake me a lasagna; leave request and I will send you my address :-)

The whole job took literally 9 minutes.
