The order arrived well-packed, no issues. Installation was easy. The instructions were thorough and straightforward. All the tube connections worked first time, no leaks. The build quality is very good. In fact, I think the design and materials for the sink-mounted water spout are undoubtedly the best I've seen, unusually elegant.

I'm happy with the quality of the water. In particular, I switched to this water filter because it gives me the alkalinized water I need while cleaning the water much more thoroughly than my previous filter did. I feel more comfortable that my water is as good as it can get.

The only minor issue is the amount of water and mess that can occur when the system is full of water and I mount a new cartridge. I'd like to be able to drain some of the water from inside each of the three cartridges before twisting them off. Then there would be no water on the floor of my under-sink cabinet. However, as I said, this is minor and very infrequent, since it only happens when a cartridge is swapped out for a new one.

For the price I paid, I find myself totally satisfied and recommend these filters without reservation.
