    Absolutely fantastic!
    I love this filter so far! First off, installation couldn’t have been easier. I’m pretty handy, but even if you’re not, don’t be afraid to tackle this. Including moving all the existing stuff under my sink out of the way, maybe 30 minutes for the filter and spout. I also purchased the mini reserve tank so I could run RO water to my refrigerators icemaker too. That took a little longer only because I had to pull the dishwasher out to run the line behind all the lower cabinets.The water quality is perfect. I have a Culligan RO system at our main house, so we’ve gotten very used to RO water. This unit was installed at our second home that is on well water. The supply goes through separate sediment and iron filters before hitting the RO, and the resulting water is perfect. There is no discernible difference between this system and the much more expensive Culligan system, except that the flow rate and pressure on the water drop is much better than the Culligan. I’m excited that we will no longer be 1 hauling cases of bottled water with us every time we stay at this home, and 2 no longer throwing away hundreds of empty plastic bottles every season. I already recommend this to a neighbor on the same well system and he ordered one too. Don’t hesitate to purchase this system.

    5.0 out of 5 stars Simple Installation w/ Great Results
    Reviewed in the United States on September 8, 2020
    Setup
    First off, I live in an area with very poor water quality. The water is poor in terms of hardness and overall TDS. These are the two primary attributes that affect taste and can easily be measured. A simple TDS meter can be had for less than $15 on Amazon. Hardness/scaling is generally noticed by water spots on your dishes, and white or green crust that builds up on your faucets. Water from my tap tested at over 500 TDS which is extremely bad.

    Installation
    As far as the installation, it really is quite simple. When they say an average person can install this in 30 minutes, they are being accurate. I took my time reading through all the instructions and watching the video installation and probably finished in no longer than 45 minutes. A simple drill should be all you need. Drilling a quick hole in the drain pipe & installing a slot for the included water faucet, if you don't already have one, are the only things that may give you pause. These are covered in the manufacturer's YouTube video and I felt more than comfortable after watching it. Many people likely wouldn't need to drill a slot for the faucet, but I did. They give you a sizing circle but I actually went much smaller as the actual faucet is smaller than indicated by the sizing circle.

    Results
    As originally mentioned, my water tested at over 500 TDS. Using the highest quality Samsung fridge filter from WaterDrop my TDS dropped by about 100 and was in the low 400's, which is still quite high. After completing draining I tested my water at approximately 100, which was higher than expected. As I ran the water a bit longer I saw it drop further. After running through some cycles the faucet started producing water that tested as low as 40 in terms of TDS. This is extremely good in terms of where I started. The system claims to reduce TDS by about 90% or more and that's right where I am at. If you have a better starting point, your results should be even better.

    Other Thoughts
    Overall I'm thrilled with this little device. My in-laws have a traditional R/O system that takes up the entire cupboard under their sink. Doing some research, these can have issues with mold growth if left unused for any sort of prolonged period. I feel much better with this system and it fits in nicely aside my waste disposal unit. This system has a water waste ratio of 1:1 meaning that for every one cup of filtered water you produce, you produce one cup of water waste that goes down the drain. This is actually substantially better than most systems I've seen but worth noting if you care about that. It produces a sort of low hum when in use but I actually kind of like it. It lets me know it's working. I drink tea almost every day and now I finally have good water that won't cause build up on my electric kettle. The taste is akin to bottled water as well.

    Additional Considerations
    One of the things that bugs me is that my fridge produces ice that ends up flaking in water. As it melts you can tell there are clear particulates in your water. These are termed as "harmless" and should just be minerals that are in your pipes but I definitely don't like it. Going forward I may pick up a second unit to hook up behind my fridge. The only challenge would be figuring out how to connect direct to the unit since it would not be directed to the included faucet. Overall I think this is one of the best purchases I've made in the past year and have been happily using the system for over a month now.

    Reviewed in Canada on September 15, 2021
    It was a great buy !! I bought it 10 months ago. The hardest part was drilling the hole in my countertop, as it was something I had never done before !! Other than that, I found the official instructions and videos not so detailed, so I had to find some help from a few YouTubers, and found some very useful and comprehensive videos on installing the systems. of this brand. I needed to drill another hole in the drain pipe, and that was the other tricky part, but it wasn't that hard, just you won't get a quick install if it is your first time drilling your pipeline and counter :)

    The best of this system:
    - There is no tank, so if you have a small counter space, this is a great choice.
    - The quality of this purified water, it considerably reduces all these bad particles, chemicals and heavy metals
    - The taste of water is simply delicious and you get it in seconds.
    - You can do the installation.
    - The price could be a bit high but for the quality and performance I found it very fair.

    Overall, this is a great product and I'm very, very happy with it!
