Product review (5 stars): Worth a Try!
I agree with "research before buying" that the fitting on the top of the filter is different that the OEM in that the OME is cut at an angle while the Refresh filter is a rectangle.  I have a LG side by side and originally my wife said it didn't lock into place and asked me to give it a try.  I gently pushed the filter up into the housing and was then able to turn it to lock it into place.  I've had it installed for a few days now.  No leaks and water taste and smells fine. Price is outstanding!
