I am very happy with this purchase. Do your research before you buy so you know what you're getting and what you really want. This is NOT an R/O block, but it does an excellent job with two-stage filtering. Our second home has city water that tastes pretty "purified". I wanted something that would be relatively easy to install and still leave us with great tasting drinking water. I would consider myself reasonably skilled, but not an expert. Took me about 45 minutes to install this unit. The instructions were very clear and all the parts fit perfectly. No leaks the first time! The taste of the water is excellent. My wife is very picky about water. According to her, some bottled water has an "unpleasant” taste. This device passed the "woman test". At the moment it has been working for about 8 weeks and without any problems. UPDATE 05/22/17: 7 months in use and no problems!
