Product review (1 stars): No good.
These were a pretty big disappointment.  I was excited to find that I could get some of these for way cheaper than the Samsung version.  I installed the first one and it made the fridge vibrate so bad that it would rattle the whole house.  I tried the other two with the same result.  I bought a new Samsung filter and the obnoxious vibration went away.  I would not recommend these.
