Product review (4 stars): Works good, except OptimIce
I hooked it up myself, and I'm only moderately handy.  I just watched some videos on YouTube.  It works.  The only strange thing is, it doesn't work when I put my fridge in OptimIce mode.  I don't know if there is a setting on the ice maker that needs to be turned on, or if it just doesn't work with an aftermarket part.
