Product review (1 stars): Buyer Beware
Although I did not have any previous issues with the standard samsung filter (Aqua-Pure), I decided I'd try this one to save a little money. I did not buy the WSS-1 filter from Amazon, but because of what occurred when I used it, I decided it was the best way to post my experience.
After an issue-less Water Sentinel WSS-1 filter install and water cycling, we were gone for a couple hours. Upon returning, there was a pool of water at the base of our refrigerator. Opening up the refrigerator door, there were drops coming from the top of the filter. I have never had a leak using the Aqua-Pure filter.  I removed the Water Sentinel filter, cleaned up the mess, and decided I'd not buy this filter again, but would revert back to the Aqua-Pure filter. After a couple days, I attempted to install a new Aqua-Pure filter. It now wouldn't fit into the filter assembly opening. Something was keeping it from engaging into the fitting as it always did before. I thought maybe there was something possibly left over from the Water Sentinel filter, but I couldn't see or feel anything that might be in the way. I subsiquently took apart the water filter assembly, and found out why the Aqua-Pure filter would no longer fit.  There is a plastic filter engagement coupler that is not fixed- it can rotate.  It appears that the Water Sentinel filter has a different locking pattern than the Aqua-Pure filter.  When I installed the Water Sentinel filter (to the full counter-clockwise hard stop), it rotated that engagement collar to a position where the Aqua-Pure filter could no longer be installed.  Having taken the filter engagement assembly apart,  I found I could take a straight slot screwdriver and rotate the plastic collar back to it's original position.  The Aqua-Pure filter could then be re-installed.
Taking apart the filter engagement assembly took some handyman type experience (as it's not very easy to reach to the back of the refrigerator with wrenches and screwdrivers), but it was doable.  I don't know if others have had this problem, but to me it was serious enough of an issue that I thought I should share it.
