Product review (5 stars): Will be purchasing again!
This filter has been installed for a week now and zero issues.  Once it was installed the air needs to be released out of the lines and then the water will flow properly.  I believe the people that say it leaked either installed it improperly or were missing the "O"rings.  The "O" rings on this filter are slightly thinner than the original manufacturer filter but no leaks so far.  My water dispenser dripped a little bit until all the air was out of the lines and now it works perfectly.  The water tastes great and no complaints from the wife or kids.

I bought another one of these filters on Mar 2, 2016.  This one is a newer version that the filter I purchased last year.  It installed without any issues and worked perfectly once I ran the recommended amount of water through it.
