Easy for blind!
We bought this and have had it a year. because my husband needs to be able to run it, as he is Blind, it’s easy to turn on as the button is right in the middle front. Picking up the carafe it auto stops. Easy for me to clean and troubleshoot. Water tastes great! Filters last! Not too big, plenty of water. A little slow on draining into carafe, but we just start it when done with and it’s ready for next person. With a pull out faucet, easily loads water. We keep it right by sink. The heat feature is nice but hardly use. Refilering it is easy. Well made. Once in a while it will seem to stop. Just pick up the carafe, and set down. Or unplug for 30 seconds and it’s ready to go. Just needed a reset. Would definitely buy again!

Great RO system & customer service
I owned at least 3 other RO systems, and this one is the best. It's design pros are: 1) The filtered water reservoir is the kettle itself, not in a container inside the system which is impossible to clean (or to inspect if it needs cleaning). 2) Its kettle is more convenient than a stand-alone kettle: you can set temperatures. 3) Pure:drain ratio (4:1) is great, one of the best in the market. 4) Its small size -- all others took so much space on my counter top, but this one is small enough. It doesn't provide as much purified water at a time, however can you really drink more than 0.8L water at once? I can just press the button again when the kettle is empty, the water will be ready for me the next time I want to drink it. 5) Not in the description, but while the RO is working and dripping water into the kettle, the moment you lift the kettle, it stops dripping immediately. I've done this many times, never got a single drop of water outside of the kettle. I've been using this through the whole winter, provided me with hot/warm water every day. Customer service is very responsive as well, trustworthy. The only feature that I wish it could have is to have a timer for the temperature, e.g. to boil a pot of tea for 12 minutes. Then this can fully replace fancy tea kettles. Another nice to have would be to preset time, e.g. filter water at 7am (so that I can have a fresh pot of water when I wake up), but actually filtering is so quick, I can just press the button and brush my teeth etc, then the water will be ready for me.

Unit not functioning after five months
I was excited to have a counter top water filter system at home five months back in April 2024 when I first purchased it. It cuts down the water to 100 - 250 TDS while my tap water has over 350 TDS although it isn't superb like below 50 TDS. It can heat up the water to hot or boiling for tea or coffee or quick oatmeal. A week ago the electric panel on the top no longer lit up even the power is connected leaving this system useless. I tried to reach out the seller as it is supposed to cover under the warranty for 5 years. No response whatsoever after I wrote to the seller two weeks ago. I was hoping to work with seller to troubleshoot the issue and get it resolved before I write any negative comments. Unfortunately, it does not work out.

Amazing Reverse Osmosis System
This product is amazing! I am really pleased with how good the water tastes and how well the machine functions. It easily paid itself off within the first month of using it as we go through a lot of water. I haven’t had any issues with it and bought it in February and use it many times per day to fill our gallon water jugs for drinking water and making coffee and cooking with. I also love the built in ability for it to heat the water very quickly and the fact that it can make tea easily with the infuser that comes with it. I highly recommend this R.O. System to anyone needing a great counter top unit that is durable and easy to use.

Best tasting water!!
I purchased this for our RV. We were packing gallon jugs of water each time we went camping. Campground water is usually gross (chemical tasting). The water this filter produces is AMAZING! In addition to the good water quality, it cones out quickly! It will filter 0.8 L in 20-30 seconds. The reservoir holds 3.5 L and produces a total of about 2 L. To heat water, you can choose different temps. It does not dispense hot water, but can heat the filtered water. Boiling 1 pitcher takes about 1 minute. Our RV has a fairly small countertop, so I specifically looked for the smallest RO dispenser with options for heating. I’m super impressed that I could find a unit that matches my size needs AND produces such delicious water so fast! One more thing, it’s simple to use—just fill the tank and push a button!

Tasty clean water from anything you put in it!
My family LOVES this filter. Our tap water is fine, but this cleans it up very well and it tastes amazing. We even took it to the stanky-tap-water beach in Florida, and it produced the exact same taste and feel as at home - I was skeptical it could pull it off but here we are! Installation was cake, and it seems to backwash the filters automatically whenever it's needed, but manually doing it is simple. No issues at all with this setup. It's a good size and fills up relatively quick with minimal waste water.

Easy to use and maintain
Overall, we have loved the quality of this product. There is some noise when it is being used but not nothing out of the ordinary. The flow has slowed down recently, and I thinking it has been a year and I might have to change one of the filters to increase the speed. One of the two filters needs to be changed every year and the other filter every two years. As per performance, it does what it has to do, however, there are times that when water is being added too abruptly, the water beings to leak. Overall, it is a good product.

USELESS EXPENSIVE COUNTERTOP ORNAMENT
Amazon shouldn't allow sellers to sell items that you can't get filters for. This coffee maker is totally useless now that I can't get filters for it. ALL THE MONEY THAT I PAID FOR THIS COFFEE MAKER AND NOW I CAN'T EVEN USE IT. NOW IT'S JUST AN EXPENSIVE COUNTERTOP ORNAMENT
