Product review (5 stars): Much Simpler Than I Feared
When I moved in, I noticed that half of the refrigerator door bottom gasket was ripped with the magnet hanging almost to the floor and the compressor constantly running. I was dreading doing this, but as a renter, the refrigerator was a "frreebie" and the owner is not responsible for repairing it.

The replacement turned out to be so much easier than I expected. I was armed with the plastic putty knife and a rubber mallet as I saw in the several repair videos I watched. It turned out, all I needed were my fingers to get the new gasket on the track. Two tips: 1) definitely soak the gasket in bathtub hot water and then dry it so the kinks get ironed out and it's so much more pliable and 2) do the two top corners first and work your way down to the bottom. When done, carefully use a constantly moving hair dryer along the gasket with the door closed to "seal" it better and wait an hour before opening the door. Good as new!
