Product review (4 stars): Good replacement at a great price!
These fit fine.  The instructions for my Samsung fridge suggested that you needed to turn the water off to the fridge before changing the filter.  This was not true.  Simple twist the existing filter 90 degrees and pull it out.  This may require pliers (as I used) or something else to improve your grip, as the existing unit is held in under a little pressure.  It rotated easily but would not pull out.  Reverse the steps to insert the new unit,  pushing in with force to seat the filter before turning it.  Because the handle is smooth, and I anticipate the same need for pliers as I had with the OEM filter, I deducted one star.  But this seems like a fine replacement at a great price.  Why a little grip can't be molded into the handle is beyond me.  Or even a hole to slip a finger through to assist with pulling it out.

Remember to run some water through the system to remove air bubbles so the wife doesn't get splashed and upset.  I had a small puddle of water after installing on the inside ledge of the fridge, maybe the size of the bottom of a drinking cup, but no leaks after.  All good.
