Your review: It does it's job. My old one lasted for 15 years.
Pros: It runs, and does what it's supposed to do.
Cons: Installation instructions were awful.I had a friend who is handy help me with the install. And they put the 4th screw behind the motor, it is impossible to mount it to the wall. When we took the old motor off, that too had the screw behind the motor, and it too was mounted with 3 screws. Bizarre mounting design.
