Product review (5 stars): Installed two years ago and still going strong.
The hardest part of replacing my evaporator fan motor was getting the old one out of the freezer.  Once I did that, swapping the motors was quick and easy.  Once everything was back together (also "fun") it started right up.

This little guy saved me a ton of money by not having to call someone to replace it or replacing the fridge altogether.  It's been almost two years since I installed it and there have been no issues.
