Product review (2 stars): Better by the installation kit
I wasn't sure exactly what I would need to work this into my water supply line, but thought I would just pick up the needed connections at my home depot. That did not go well at all. The 1/4 tubing it calls for was not something I could get connectors for there (though they sold the tubing). And even after connecting it the connection at the filter leaked. I'll probably just buy a filter at the store that uses more reliable fittings.
