Product review (4 stars): Can stop your icemaker from working.
Update:  I thought this filter was preventing my ice maker was not working.  That was not the issue.  A simple fix found on youtube. I think I will stick to Samsung filters anyway, to be safe.

I received it in 2 days per Amazon Prime.  Installation was easy as the old one. No problems.  I did run water through it for about 7 to 8 minutes to clear out the initial carbon stuff.  It appears to be working good.  Great alternative to the expensive Samsung brand.  I recommend it.
