Product review (5 stars): So Happy I bought this one!
Got my Itty Bitty water filter today.  It's the perfect size in my small kitchen apartment after looking at many types on Amazon.  The directions for installation were clear and simple.  I had it installed in less than 10 minutes!  Super easy for a not-so-handy type like me.  Turned on the faucet, and ran until water was clear in about 2 minutes.  Let it run for 5 minutes like instructed, then took a sip of the clean, clear water!  No more plastic bottles to recycle, or go into the ocean!!
Happy happy!!
