Product review (5 stars): Extremely easy to install and the taste improved immediately
I read a lot about going with a cheaper knockoff model and more than likely those perform the same as the GE.  However, since Amazon Prime had a reasonable price I went with it.  Extremely easy to install and the taste improved immediately.  One thing to note is that it won't come with instructions and actually refers you their website.  It's not rocket science to install so I get that no paperwork is included.  However, you'll just need to make sure that you run water through it for about 5 minutes or so until you see crystal clear water.
