Product review (5 stars): Cost effective; straight forward intallation
I chose this filter because it has been connected to the refrigerator at work for over two years and we have never had any issues with it.

A couple notes:
1.  It takes up a lot of space behind the refrigerator, so I mounted it in a cabinet next to the fridge.  This resulted in several advantages including easy access to the filters (don't have to pull out the fridge to change the filter), and an easy way to watch for leaks (so far, there aren't any).  The attached photos show my installation.
2.  I opted for the expensive LDR 509 5175 Pex 25-Foot Ice Maker Connector tubing.  The tubing is flanged on both ends, so the connections are secure and leak free.  The tubing can be cut in the middle since the straight ends fit into the filter.  Inserting the tubing into the filter required a significant push, but resulted in a very secure connection.  I didn't need 25' but the extra cost was worth the worry free installation.
3.  The water in our town is quite good, but has a strong chlorine taste and smell.  This filter did an excellent job removing the chlorine, significantly improving the taste.
4. The instructions recommend securing the filter to the wall using a block of wood (see attached picture).  This worked out very well since I was able to secure the block to a stud and then mount the filter to the block; however, attaching the filter using mollies would probably be just as secure.
