Product review (5 stars): Seems to work great!
Obviously its pretty hard to test filter vs. filter, but it seems to do the trick!  Our fridge only uses this for ice (which lately, I have been turning off), so we don't push mega volume through it.  Furthermore, we have very good water quality.

I will say, I recently ordered two.. and one came without the protective cover... but seems to work well anyway.

At the price, definitely recommended.
