This filter is great and with the clear housing you can see how well its working. I would have given it 5 stars if the installation "hardware" had been better (I couldn't stop the leaks)... I simply went to my local plumbing supply and bought "shark bites" (be sure to take the fitting with you to get the right part)...using the "shark bites" (a little pricy but, so worth it) installation is easy and takes very little time.
