Product review (5 stars): I would recommend
Worked great on my ice machine.
Easy to install
I had never put one in, and I'm and idiot, and didn't flush it (run water through it to clean out the carbon)

I just dumped the first few batches of ice, and it works great.
Ice was never grey or cloudy, so not sure if it's really required, even though the box says to.

Just take off the little grey rubber things on each end of the filter, cut your little tube going to the ice machine, and push the tubes into each end of the filter.  Pretty easy, even a moran like me figured it out.

Ice used to be white and leave white powder at the bottom of your glass.
Now the ice is clear, and leaves no ice dust.
