Product review (5 stars): perfect replacement on whirlpool fridge.
One note that the unit must have an internal temp sensor before it will allow water in the system it took a good long while (id estimate 45 min) or so before it kicked on the water supply. (This is NOT noted in the limited instructions) Decent instructions not great but ok...if you aren't adept find a tech savvy friend to help you install this.  And don't freak like i did when it doesn't fill up the ice tray with water immediately i thought i got a dud at first.  Give it an hour to chill out (pun intended) .  You'll be on your way making that precious summer ice in little or no time....if you have to hire a pro to install it should take less than 1hour i.m.h.o....any longer and they aren't up front with labor costs.  My honey is lucky i can install this type of thing.  Been working great for about two months now.

UPDATE FEB 2014!!!
Still working strong...makes lots of ice no problem  great value ...one small detail is this unit sometimes gets ice buildup on a small part near the inlet tube... and it will stop making ice because the metal stopper becomes stuck in the "off" position....not a big deal just annoying maintenance every two months or so... you can chip off the ice and it seems to work fine for another 2 months...then chip/repeat...works fine again.
