This thing is great! It arrived well packaged with most everything needed to install. I had to pick up an adapter to connect the hose to the current valve that was installed for an old filter system but other than that install was a breeze. I also already had a return location for the drain and a hole in the sink for the tap, if you don't it will be a little more labor intensive. Also I have a long background in plumbing, if you don't feel comfortable doing it yourself I am sure a plumber won't charge too much to install this for you. The system works great and produces nearly perfect water. So pure in fact, we added an additional filter to reintroduce some of the minerals that this removed just to enhance the taste. The system is very quiet and I only notice it when I happen to be in the kitchen late at night with no tv on and it is running a backflush cycle. It seems to be extremely well made and the company has been around a while, so I am not afraid of not being able to get new filters in the years to come. Overall I couldn't be more satisfied with this system.
