I love this and it was pretty easy to install, I had a confined space and it was a little tight but, it worked out perfectly. I had to add 1/4" nylon elbows to the faucet and tank ports in order to get it to fit.

It took me 3-4 hours to install it. The biggest challenge is making the hole in the countertop (granite). I had to purchased the Milwaukee 1 in. Diamond Plus Mini Hole Saw $36. Pros. Water tastes super clean. Cons. Every Time that I fill up a glass with water, the filter valve keeps wasting water for hours. I have to turn off (10 seconds) the cold water faucet to stop the spilling.

few months ago water started spewing out of the little hole on the side of the faucet

Water quality is great. One of the sumps had a dribbling leak. Only resolution was to use plumbers tape. Best part, ending $30 monthly water delivery. Used Home Depot home services for the install, and all went well.

Installation took me a couple of hours, give or take, only because I took time to read completely through the instructions before beginning in order to get a thorough understanding of how it goes together, and I wasn't in a hurry to get it done. I'm a professional handyman with lots of plumbing experience, so I probably could have done it in an hour or less if I had to. The printed instructions could be more thorough. I recommend watching the video on the Aquasana web site, because it shows things that are not in the printed instructions. For example, the flow restrictor that must be inserted into the hose that connects to the stage two filter is mentioned in the printed instructions, but not identified. It's a tiny tube that fits into the hose that's connected to the stage two filter. Not knowing what that tiny tube was, I didn't install it. Thus, the system made a loud, horrible noise in my sink drain pipe when filling the tank, which we could not live with. We decided to uninstall and return the system. Fortunately, however, I watched the video on the web site, in which the flow restrictor was identified, and it clicked in my mind. I installed it quite easily, and it eliminated the noise. Also, the printed instructions make no mention of the plastic ferrule and tiny copper tube insert that are used when connecting the hose to the plastic elbow that attaches to the top of the tank, but I recognized them because of my plumbing experience. Minor things that can make a major difference. Overall, though, my wife and I are very pleased with the system, and we are much safer because we're no longer drinking chlorine, which is necessary to keep things from growing inside the pipes, of course; nor are we drinking fluoride and other contaminants. We are also protected from bad actors who might try to deliberately contaminate the water supply, which has been done before. We appreciate the range of contaminants that this system removes, and we would recommend it.

Water taste exactly the same as without filter i feel as if i could have bought an inline filter and been fine!

The tank was a little bigger than our old one so we had to move stuff around to fit under the sink, but it works great and fairly easy to install.

very good, met my expectations. occasionally seems a little noisy. certainly improves the taste of our well water.
