I would like to start Thanking WaterDrop Manufacturing an Excellent system which looks sophisticated on CounterTop, Compact in nature and most importantly good water supply that tastes excellent. I used to have older system that came with water softener(Dupure) and it is good cannot say great since it is my first RO system and did NOT know the difference. After 5 years of paying a ton of money for filters and to replace them them additional fee for the technician, I finally gave up the thought of spending close to $500 to replace the filters as my water line(RO) is NOT giving me any water. Other weird thing is I need to fill in Air in the reserve tank every Winter, if not the water does NOT come out faster enough.What I think is great about this system X121: It has 2 Modes Energy saving which saves power for me as it runs on electricity, regular mode which I can use during a family gathering where lot of water need to be pumped in less time.2: The display shows what is your water impurities as the water flows out, it is usually for me 19 to 21 which is the best possible water you can drink.3: Compact design gets under the sink occupying less space.4: You can set the amount of water that should be dispensed every time, this is an amazing feature if you have kids and sometimes dont pay attention to turn off the water.5: Changing Filters is a breeze and dont need to pay the Technician $150. Also you need to schedule and stay home for the repair.6: Most importantly the Customer Service, they are amazing and I will NOT be able to say how much they helped in installing the system and questions I have to make the system up and running.In my case I have to involve a Plumber to replace the Old system with X12 as our old system has complex installation. But there a videos and manual that can be followed easily to setup the system. For now I am Happy I made the move and water tastes like water should.Caution: If used to drinking tap water initial days you can feel it is different and this is because your taste buds are used to a taste and anything different you may NOT like it and body takes time to adjust.I posted the review to help others who delay things like me and wasting money trying to keep the old system running and not sure which system to move to. In my case this is the Best decision, everybody has different budgets so pick a system based on your needs. Also Waterdrop occasionally has deals on the systems, so subscribe or visit their website to save some more money.

I’m very impressed by the quality, fit and finish of this unit. Installation instructions are excellent and takes around 30 minutes to install. Once installed the functionality is excellent as well as the water quality and taste. I especially appreciate the units form factor which fits neatly and looks nice inside the cabinet. When the filters need replacement they are easily accessible by removing the front cover.

One of the best things we’ve added in terms of household items. The water tastes great and the convenience is life changing. The water flow rate on the X-12 is surprisingly fast. We don’t ever get impatient filling up our coffee maker reserve tank, pots, large pitchers, etc.It’s relatively silent. When dispensing water, I only hear the water. Afterwards (the timing varies), I can hear the under sink unit draining into the pipe, but it isn’t very noticeable. The sound of the water dripping into the sink drain is louder than the unit. The lower you place the unit’s drain tube on the sink pipe, the less drip noise you’ll hear. My wife and kids don’t even notice the noise.I’m not that handy and was able to install myself. The instructions are helpful and I found many videos online.I had questions on the faucet unit. Customer service was very responsive and helpful. Top notch support along with a quality product makes this an easy five stars.

We've been using a Culligan RO system for many years, but buying replacement filters online isn’t an option—they can only be picked up in-store. Plus, having Culligan replace the filters costs nearly $450 in California. So, we decided to switch to a new RO system that’s easier to maintain. After extensive research, we chose the Waterdrop X12. Here are the pros, cons, and some hidden features we've discovered:Pros:- Certified Water Quality: This system has passed multiple certified lab tests, so you can be confident it effectively removes contaminants.- Tankless Design: Minimizes the risk of bacterial growth (our old system had a tank, which needed periodic sanitization—costing more in maintenance).= UV Sterilization: Unlike many other RO systems with 3 filters, the X12 includes a UV sterilizing light for added protection.- Smart Monitoring: Both the faucet and main unit track when filters need to be changed—a great feature when life is already busy.- Reputable Company: Waterdrop is backed by a large company with years of experience in water filtration. This was important to us, as many RO systems on the market are from startups, and I didn’t want to invest in a system from a company that might not be around in a few years.- Award-Winning Design: The X12 won a Red Dot Design Award. Even though it’s installed under the sink, it’s nice to have something that looks great!- Excellent Customer Service: Initially, we spoke with a representative who couldn’t answer all our questions. However, we were later connected with a staff member who provided detailed responses promptly, even within 24 hours when out of the office.Cons:- Wobbly Faucet: As some reviewers noted, the smart faucet wobbles. Some have 3D-printed adapters to stabilize it. Hopefully, Waterdrop will consider adding a fix in the future.- Pricey: This is one of the more expensive tankless RO systems, but the unique features make it worth the investment. Plus, Waterdrop frequently offers discounts on their RO systems.- Noise: It does make some noise, but it’s only noticeable when the room is quiet, and it's not a dealbreaker.Additional Thoughts:Some buyers mentioned that the initial water flow is too strong, causing spills. I personally found it acceptable, as the higher flow is part of the appeal. If you prefer a slower flow, the user manual explains how to enable energy-saving mode (restart the unit and press F2+F3), which also reduces the flow. There’s another mode not mentioned in the manual called "faucet mode" (restart the unit and press F1+F2) to reduce the water flow without affecting energy use.Overall, we opted for the X12 due to its faster water flow. If you prefer a lower flow, models like the X8 or G800 might be better options. I hope this review helps you decide if the Waterdrop X12 is right for your family’s needs!
