Product review (5 stars): but it's useless if you don't clear the drain
We did our homework and found videos showing how to install it in our Whirlpool GB2FHDXWS07 It wasn't difficult to install, just taking apart the inside of the freezer so we could defrost the block of ice back there was a pain, but it's useless if you don't clear the drain. It's been several months now and not one bit of ice has built up in the bottom of the freezer, no more puddles on the floor! Yay! Totally worth it.
