Rated 4.0 out of 5.0 by Phazor So far so good, and plastic connectors people complain are easy to solve
I installed this filter under kitchen sink like many others. With filter in, it still has good flow, but somewhat reduced.. It claims good filtering properties, I don't have means to verify it. The water tests better with fitler on. When time comes to replace the filters, it is designed to be easy to do. It has a scale that tells how much filter life is left, which is good.
The plastic fitting that goes to the water supply, do leak because it's threaded section is too deep and doesn't allow enough compression for seal. My initial solution was to add some teflon tape to the male thread, which worked. But later I figured I could chuck that plastic connector that came with the product and use a brass 3/8 nut with compression sleeve and brass insert for the plastic pipe to connect to the 3/8 shut off valve output, which was meant to receive a compression fitting. And I did that, worked fine. The output side fitting that came with the product connects without problem to standard 3/8 faucet line. I later connected to a dedicated filtered water faucet which had 1/4 tube connection. For that I used 1/4 copper line to the faucet with the compression fitting, and 1/4 to 3/8 plastic quick-connect fitting from home depot which again didn't need to use the fitting came with the product there either.

I purchased this filter after speaking with the store associate - easy to install and excellent tasting water right out of my kitchen faucet - water pressure is strong and didn't have to drill into my counter top.

Rated 4.0 out of 5.0 by AZVoter Does the job
Bought this filter to improve the taste of Phoenix municipal water. I wanted a decent filter at a reasonable cost that was easy to install. This filter checked all those boxes. Plus it is great to not have to deal with a dedicated faucet (as in an RO system). Don't believe the reviews that say the fittings are cheap and/or that they leak. Just take your time, follow the directions, be sure you insert all the hose ends fully into the connectors, and all will be well. In five months of regular use, no leaks, and the filter gauge indicates the filters are only about 1/3 through their lives. Couldn't be happier.

Rated 5.0 out of 5.0 by AC Great product!
We love this system! Was a little pessimistic at the thought of it, but love, love the ease of filling our kid's sport bottles. Also great when mixing large pitchers of drinks, or simply grabbing a glass of water.
As far as installation, this was installed during a kitchen remodel, so our contractor did it. No feedback regarding ease, but we've had zero issues with leaks, etc.

Rated 1.0 out of 5.0 by davemon67 Tastes like chalk!!!
Use a TDS Meter, we have really bad water measured .0389 PPM
compared with Arctic water at .0018 and Distilled water at .0000 with the same meter
this was after just 3 weeks and the meter indicator only had moved 1 place... High Priced Junk!!!

I am echoing the review that faulted the plastic fittings for leaking. I gave it a shot, but the male fitting kept leaking.

Rated 5.0 out of 5.0 by Joe Great Filter and a snap to install
I installed two of these filters, one in my house and one in my sons apartment. Took all of ten minutes to install each. When my son moved I transferred his to his new apartment.
I set mine up before the water supply to the refrigerator. This eliminated the need for a dedicated 'refrigerator' filter which saved me about $100 per year for those filters. Still working on the originally installed cartridges after one year. My son needs to replace his every 3 or 4 months due to the dirty water supply in his building in NYC, but at least he is getting clean water now.

Rated 4.0 out of 5.0 by R1ceBurner Easy install if you have the right parts
Installing Kube should take maybe an hour tops. If you have all the right parts. What should have been a quick install, turned out to be a day long ordeal for me.
I followed the instructions and made all connections then turned on water to let it run for the recommended length of time to flush carbon sediment from the filters. This ended up clogging my faucet and stopped water flow completely because small bits of the carbon stopped up a part of the actual faucet connection. I had to replace my kitchen faucet...
To avoid this I highly recommend not making the final connection (from Kube to faucet) until you turn on the water and let it run for a few minutes into a bucket or the sink. Then make the connection once the water runs clear.
Tubing: used a new blade and split it in half. This gave me enough tubing to move the unit as needed. When you connect the tubing, push in and make sure it is snug. You should feel it click. If it is not snug water WILL squirt from the fitting.
Overall we like the Kube, water is clear and tastes better. Install is easy and shouldn't take long. We were able to also run the ice maker water line after the Kube, so we now have filtered water for our ice machine.
