I LOVE our waterdrop system!
I LOVE our waterdrop system! The hot water dispenses HOT water in seconds! No need to wait for the tea kettle to heat up. The cold water is room temperature (just the way I like it), but we fill the water picture and refrigerate it to get the water really cold for everyone else. We've gotten rid of our cold water dispenser and we no longer buy water bottles. Another step toward going green!!

It is a little bulky but overall it's a great unit it would be better if it was a little bit smaller and if it was a little bit less pricey.

I received excellent support
I received excellent support in helping me install the RO system into my small under sink area. It is easy to use, quiet, and our water tastes noticeably better. I feel much safer knowing that the filter is working.

It works really well to filler
It works really well to filler and heat water. My tea tastes amazing and I turn it off when I go out of town so I know I won't be using it.

We use this product now
We use this product now instead to buy 5G purified water from supermarket. We also had a two filter system under the sink, but now we replaced it with this RO system. Overall we are very happy with the product, which can also supply hot water for tea and coffee

I purchased it to get cleaner
I purchased it to get cleaner water for my skin condition. The quality test verification sheet provided on the website builds trust to buy this product. I tested it with a ppm meter at my end too. The quality of water is great. Great job! Only complaint is that hot water is produced only a couple of glasses at a time and you have to wait every 15 mins for the water to heat.

Game Changer! We now drink
Game Changer! We now drink more tea than ever. We no longer have to boil water for a bain-marie to make our beloved Cr猫me br没l茅e. Just a splash of instant hot water while doing dishes means no more waiting for the regular faucet to get hot - saving time, water, and money! This will the first thing I install in any future home!

The product is a game changer
The product is a game changer for people/families. In modern days, we rely on bottled water for convenience. This can help the environment and provide great tasting water at the same time. It doesn't take up space like water coolers; which are quite common in even in the best tasting-water cities. The added hot water feature adds a convenience for instant hot water. We have used hot water feature to make hot, instant coffee, and to speed up boiling things on the stove.

The waterdrop k6 is an amazing device. Instant hot and room temperature filtered water at your fingertips. The design of the spout is great with touch controls. The filter and water tank under the sink is a bit large but not a deal breaker.
