Product review (3 stars): Works, but slow drip at dispenser.
Works but slow leak at water dispenser after installation....one drip per 4.5 minutes.  Did the calculations and that's 1 gal per 153.6 days.  Annoying but I'll live with it.  Here's how it went:

Received shipment on 12 Jan 15.  Installed on 2 Feb 15.

The installation instructions for my Samsung fridge say you must turn OFF the water supply before remove and replace.  This makes the procedure a little more difficult than initially presented by the salesman of the fridge.  You have to pull the fridge out from its position to get to the water supply.  After I did that, I turned off supply and went to the front of the fridge to remove current filter.  Takes about 20 pounds of pressure using your fingers to push in and left turn the filter.  At first it didn't move, then I put more force into it and it twisted free.  Probably even harder if you leave the water supply on!

Now for the replacement.  I noted everything looked the same on the top of the new filter except it had a small square shaped opening instead of a round one like the Samsung filter.  Hmmmm, will this cause a problem I thought?  Looked into where the opening was going to attach to the fridge and got an idea of where the edges would catch and tighten when installing.  Slid the new filter as straight in as I could to the target (inside attaching area), pushed and turned to the right.  It took two half turns before I felt a click and it seemed snug.  Then went to back of fridge and turned on water supply to full on where it had been during original installation last Jun 2014.  Then as per Samsung fridge instructions, ran about a gallon of water through the front dispenser to get rid of air in system.  When I finished I noted that the water dispenser was having difficulty turning off.  There was a short duration stream of water after shutoff.  This was new and was not an issue with the original Samsung filter.  I also noted a drip afterwards that ran at about one drip every two minutes.  I checked the inside of fridge for leaks and found none.  Went to back of fridge and decided to turn the water flow valve to HALF of full on.  This BTW is where I had the setting for my old fridge.  Figuring this would help the shutoff and drip rate, went back to the front to test dispenser.  Sure enough, extra flow after shutoff had stopped.  But, the drips kept coming, although now they were at one per 4.5 minutes.  Pushed the fridge back into position and kept watch for a while to make sure I didn't have a big leak.  None has materialized after a couple hours.

Not ideal, but if I loose one gallon every 153.6 days, it will do.  My only concern now is how much of a leak do I have into the two ice makers?  Only a few days will tell.  And, maybe over time as the sediment accumulates in the filter, the drip rate will go down.  We'll see.

Overall, OK, but not as good as a Samsung filter.
