Product review (4 stars): Worth it
This was SO EASY to install. It's like plug and play.  Plug in the 1/4" lines and you are done.  Used this on my fridge icemaker line.  I would recommend a slightly more expensive filter since this is the very basic one and others filter out a lot more stuff. I didn't see that in the write up.  Next time, when I replace the filter, I will upgrade.  Also, installed a flush valve kit in order to purge the filter.  Really, couldn't be easier. I am a 61 yr old grandma.  The hardest part is fastening it to your wall or cabinet and that is carpentry 101.
