Product review (5 stars): Great Value
I have had the filter in my fridge for 2 days, and no sign of leaking. It's important to bleed the lines for 5 minutes after installation (as the instructions indicate).
I think people with leaking problems skipped this step.
I also read some reviews complaining about water flow.  Mine is flowing great.  At least as good, if not better, than my old filter - that I paid over twice as much for at Menards.
