Product review (4 stars): Slightly longer than OEM
The WSS-1 replaces the stock filter at a fraction of the price with no leaks.

One small issue I had is that it is slightly longer than the stock filter.  For me this meant that rather than simply moving a few items out of the way to replace the filter I had to completely empty the top shelf and remove it from the fridge.  Once it is installed there is enough room to replace the shelf.  Is the savings over the OEM filter worth this small inconvenience?  Probably.

Also (and this is really a nit), the mark on the stock filter indicating that the filter is fully seated is absent from the WSS-1.  This isn't a big deal, but I liked the positive confirmation that the filter was locked in place.
