Product review (5 stars): Very simple install, works great.
I was skeptical of using a generic ice maker that didn't have the power switch so I went with this one.  Installation was pretty straight forward. I reused the original water tube and funnel so as not to break the seal around the tube.  You also need to reuse the old ejector for some models so keep your old ice maker.  Just let it make a few batches before fiddling with the cube size adjustment.
