Product review (4 stars): Tricky to install
These do indeed appear to reduce the vibration noise generated by our large freezer-on-the-bottom fridge. But here's the thing to be aware of... The thought that you can put the pads under the rear rollers and slide back into position (as per the instructions) is a farce. Between the weight of the fridge, and the rubber of the pads, they simply do not slide on the floor. At all. They sit put and the rollers simply roll right over the small top lip of the pad. I even tried to oil the floor, hoping they would glide on a slick surface. No, Ended up having to place the fridge in place, and with the aid of a helper, tilt it forward and push the rear pads into place with a stick while looking under the fridge with a flashlight. Then (much easier), tilting the fridge backwards and placing the front pads in place. Bottom line is this... they do seem to work well, but installing them was a pain in the neck. Almost too much so.
