Product review (4 stars): May need adapters
Just so every one knows you may have to make a trip to the plumbing section of your nearest home improvement store.  The line coming out of my wall to my fridge is a pvc ice maker/ water line with metal connectors.  Youll need to buy another one of those plus adapters to connect them to a 1/4 inch hose to connect to the filter.  In my case this wasn't just a 15 minute plug and play.  Dont forget to buy plumbers tape, itll leak if you dont.  But its connected and seems to be working.
