Product review (5 stars): This unit works great even though my ice level detector rod was different.
This unit seems to be of decent quality and functions perfectly for about a month thus far.  I was worried the mounting tabs were plastic because they were white in the picture instead of the black metal of the original I took out, but they are indeed metal and the unit works just fine.  I was also worried because the small metal "ice level detector rod" it shows in the picture did not match mine, however, that was simple to change back to the original one to make it work with my particular fridge, it just slid right out and the old one slid right back in its place.  Other than that it was just 3 screws, one connector, and sliding the thermal fuse into the little tab in the back.  Piece of cake.  Also make sure you line up the water fill tube with the inlet as you set it into place to fasten it.
