Great item. Worth the effort to install.

So far, so good. The install would have been really easy but I added a T in the line so I could feed my water & ice maker in my fridge. A little problematic but it is now working good!

Easy to install, great water taste, excellent flow

Deciding between RO and non-RO was an issue, but I'm on municipal water that has relatively low dissolved minerals, so I'm really wanting to get rid of chlorine taste. So, I don't need an RO system, and could probably have gotten by with a simple single filter like a refrigerator filter, but I wanted something just a little more.I decided on this because it's a single unit with a simple installation and minimal fittings. The toughest part was drilling another hole in my granite counter. The kit came with the "T" fitting, teflon wrap and all the needed bits and pieces. Install was simple, and I only had to tighten one fitting when it was installed. I would say the hole in the counter doesn't need to be as big, but the 1-3/8" standard hole was workable.The water tastes like the bottled water I've been buying, so that's a plus. We drink a lot of water, and fill sports bottles frequently, so I was very happy that the water flow is very fast and consistent. I may try to get a different spout at some point, because I don't need this spout to be so tall, and it's removable. Overall, there's nothing not to like about this setup if you're just looking to get bad flavors from your water.

High quality product, brilliant filter change process

You can tell this is a quality product just by the way everything “feels”. Plastic housing and tubing is all solid, and high quality metal valves are used for the sink/spout connections. Even the packaging materials were of a higher quality than what you usually see. Installation will take 20-30 minutes assuming you have standard sink connections and a hole already drilled in your countertop. Directions were clear and easy to follow. In addition to the high quality filters, the biggest benefit to this (for me) is the process for changing filters. Rather than the large filter “tanks” that you see on other products (which always end up getting nasty and needing extensive cleaning), you have filters that twist in and out from the side, super easy and much cleaner. Only had it for a few days, so can’t comment on longevity, but I will update this review if something changes.
