My buddy Nick asked me if I like it. Here is my answer.The water taste is exceptional, and I am upset that have not purchased the system years ago. I like the compact design so it fits under sink without any issues. The lack of tank is a great plus since I know the water is always fresh. The productivity of the system is decent, so it fills my coffee pot about 25% faster than my refrigerator filter. I am happy with the purchase and plan to buy another unit for my second home.There are some CONS that I had to mention: 1) installation instructions are inaccurate is a way that they do not instruct user of three pre filters that are incorrectly installed. These filters are still packed in plastic, but are installed in the systems as if they are ready to use. Instruction does not contains step to disassemble filters, remove wraps, and place them back. So I had to find it in a hard way, after pressurizing the system with water and realizing it does not work. So I had to cut water to the house to discharge the pressure and fix the issue.2) the system has notable delay before pump starts, so when you want to fill a glass it takes about 15 seconds during which water flows slowly before pump kicks in. I am used to it now, but still consider this an issue with engineering design.3) the system has no monitoring gadgets that would measure water quality and alert you when it requires attention. If this is optional product add-on I would like to see it.
