The system is very good, however I offer the following improvements that I feel could be made; Each under counter sink area is different. In our case it was necessary to mount the filter system on the left side of the cabinet. That would have been no problem had you supplied sufficient tubing. I suggest you put at l;east 4 feet of each size in your boxes to allow for that set of circumstances. As it were, I had to go out and purchase tubing to complete the installation. Secondly. I mounted the filter system a bit higher on the cabinet wall to keep it out of the way. It would be helpful if you would place the red light in the front portion of the unit so it could easily be seen from any angle.
I was tired of buying the Pur water filter for my kitchen sink faucet. Also having that filter on my kitchen faucet got outdated when I replaced my faucet with a faucet sprayer all in one, so the Pur filter was not an option anymore. Very pleased with this 3 stage water filter by Aquasana. I installed this myself. Everything you need comes in the package. I am a pretty experienced do it yourselfer woman. The hardest part of the installation was removing the kitchen sink drainpipe to be able to "fit" under the sink.
Pros: Clean taste, Easy to clean, Easy to install, Long lasting filter
