    • Makes the local water drinkable! (enjoyably so even)

I think that the water from this unit is very good to drink WITHOUT the remineralization filter, but the 'texture' of the water is better with. The typical TDS out of the cold water side is about 50. It sometimes drops lower. That number is AFTER the remineralization. Our water smells awful and this by its self makes an RO system a MUST. I use this system for my sink and generally fill glass bottles with water and refrigerate over night. The water is similar to store purchased "spring adjacent" water. When making instant soup or oatmeal the hot water is handy, but it doesn't get to the hottest temperatures. The device locks the temperature at "considerably lower" than 203. Overall I like the way this system works and feel that the water quality difference is superb. The installation was super easy and the videos helped a lot. The hardest part of the install was drilling a hole in a quartz counter. My only other minor issue is that all of my fixtures are matt black and a Waterdrop doesn't have an option for an all black faucet. ... show more

    • Great unit and great customer service!
Color: Black
Bought this in October and have loved it. Wife and kids drink tea regularly and this has worked great for consistent and reliable hot water. We have very hard water and this unit dies a great job cleaning the water before it hits the heater. No weird smelling water like our old unit. Unfortunately, it started turning the heater off randomly a couple months ago which became increasingly more frequent. I finally called their support. They answered, created a ticket and were immediate in their response. After a couple weeks of troubleshooting via email they sent me a brand new unit free of charge. Great customer service, which is what it is all about for me with a product like this. Highly recommend it! I looked at instant hot water heaters from many other brands for more money and they didn't include the great reverse osmosis filter! ... show more

    • Amazing water filter
Color: Black
The media could not be loaded. I wanted a water filter that also dispenses hot water and this exceeded my expectations. I was worried at first when reading some reviews on issues with the hot water but I find the hot water to work perfectly. Water is hot enough for coffee, tea and instant noodles. There's no wait and is truly instant. Water also taste amazing and flows fast enough. Definitely a game changer for me since I do not like drinking cold water in winter especially in the mornings. Installation is not too difficult too. Removed our hot water kettle and never looked back. Highly recommend anyone who uses hot water regularly to get this. ... show more

    • Very effective RO filtration system.
Color: Black
The K6 is very effective; it reduces our TDS by 90%. It does not take up much space and is also easy to install. The following are just from my experience as a lay person and should in no way be taken as recommendations to anyone to do the same: 1. Like many other homes, ours has only two outlets under the kitchen counter, one for the dish washer, the other the disposal, each is required to be on its own power source. Our solution is to use a two-outlet air switch, which, by only sending juice to one of its two outlets at any given moment, satisfies the building code. 2. We decided to put the dish washer and the disposal on the two outlets of the air switch. This is because, if the K6 and the disposal are put on the air switch outlets, every time we use the disposal, the power to the k6 is cut off by design. When the disposal is disconnected and power to the K6 is in turn restored, the K6 interprets it as a hard resetting and does a very energetic flush. We figured too many hard settings might not be good for the health of the K6. Besides, the strong flush would send water splashing up the drain into the sink (unlike the K6's regular flush after uses, which is very gentle). 3. Regarding how to get cold water/turn off cold water, the Instruction Manual says on Page 9: "Touch the cold water key to get or turn off cold water." I thought this meant it takes only one touch of the cold water key to get cold water. It turned out, however, (unless one has used the system seconds ago) it takes two touches. At first, I thought there was something wrong with my K6. But further research by watching other K6 owners' videos has led to the conclusion that two-touch is actually normal: the first touch (of any key) wakes up the system and the second touch (of the cold water key) gets one the water. My confusion was caused by the Instruction Manual which does not mention the need to wake up the system anywhere. All in all, the K6 is a very nice RO filtration system. I only wish the Instruction Manual may be improved. I highly recommend this system. ... show more

    • Hot filtered water 24/7
Color: Black
Took me about 2.5 hours to install. Be careful when drilling the drain hole on the drain pipe, I drill right through the other side lol. The product itself is well designed and made.

    • Dangerous! Can’t turn off hot water because touch buttons are bad! Even dry it doesn’t respond😭
Color: Black
I splurged on this but the touch button design is so bad I need to write a review. I’ve only had this for a few months but the issues feel like I’ve been dealing with this for ages. The touch button is the only way to turn off or on anything for this. There is no safety switch or shut off. If you turn on the hot water, there’s very high likelihood you won’t be able to turn it off. This should get recalled to be honest. The safety lock is a joke since it’s also touch button. ... show more
