Review: Does its job - If you're shopping for this, you probably know pretty well what it's for and what issue it could potentially solve. Obviously, it only works for select freezers, as it's designed in a specific way. So the question is: does it work or no? And yes, it does work. It solved my problem completely. No more icing up for my freezer.
Review: Easy install and solved icing issue. - Easy install my fridge kept icing up and after install no more issue with that. This from what I understand is a sensor that turns on a heating element in fridge so it doesn't ice up at the back of the fridge and cause ice to build up. Easy fix if you are a d.i.y person. Like me.
