Product review (4 stars): had the inline ice filters - bought this instead
The inline Culligan icemaker filter that I had has the same quick connect feature. The connection is so strong, that I literally had to take the filter connections apart with a razor to disconnect the old filter each time I replaced it.  One thing that Culligan doesn't tell you, is how to disconnect your pipes from the quick connections.  After years of this, I am convinced that I can rely on the quick connects staying connected.  That made me buy this filter.  Same Culligan quality, but no need to mess with having to remove the quick connectors each time.  Installed this filter in our basement, underneath our refrigerator, but above the drop ceiling.  No leaks, and much easier to do filter changes.

Update 12/31/14:  We just got a new Frigidaire refrigerator/freezer that has its own water filter system built in.  Frigidaire charges $30 for a replacement filter, vs the replacement filters for this unit which are about 1/2 that.  I decided it is more economical to pay $45 one time to Frigidaire to get a bypass filter (it looks like a water filter, but it is just a pipe in the shape of a "U" inside a filter housing that does not filter the water at all) and continue using this Culligan to filter my water and Ice. As I already said, these are more economical + they last longer also.
