Product review (5 stars): Easy to Install, Ice Tastes 100% Better
This was easy to install, as easy as crawling around under your kitchen sink can be. It's advantageous to mount a small piece of wood to the inside of your cabinet walls first with plastic anchors so that when you mount this, it doesn't pull through the thin cabinet walls. I used a 6" x 6" x 3/4" piece of pine, a scrap from mounting my sink water filter. The push-to-connect fittings were easy to use (make sure you cut your tubing as square as possible).  Mark your holes first and pre-drill since you're going to be uncomfortable trying to tighten the screws under your sink. The filters are cheap (though I had to wait on it to arrive from Canada). It does come with a filter, but I like to keep one on hand.
