“I love the space utilization of this product. No more large tank sitting under the sink and wondering how offen I should clean the tank.
Also, it is nice to have the indicators visible on the countertop with the RO faucet.”
“Water flow is not good. It takes 5+ seconds for water to start. 6-8 second glass fill rate advertising is fraud.
TDS in water is not consistent. It varies from 5 to 100+ Ppm, shown by the water drop faucet itself. 100 ppm water doesn't taste great and I have to often throw it out.”

“Almost fully satisfied, water tastes clean/great though the one thing is the vibration when the D6 unit is called upon for filtered water. Thus cannot give a full 5 stars but 4.
Almost perfect Waterdrop!”
Dear Ray,
Thank you so much for choosing our product and sharing your valuable user experience with us. We appreciate it very much! Please allow me to explain that because a tankless RO system requires an electric motor to add pressure, there should be a low vibration sound. However, if you feel the sound is more than noticeable and the flow rate is questionable, please contact us through the info below. We will provide a professional and satisfactory solution for you.
If you have any other inquiries, please feel free to contact us. We will always be there to provide satisfactory solutions for you.
Kind Regards

Dear Charles,
Thank you very much for sharing your experience with us! The higher TDS of the initial water flow when turning on the faucet is a natural phenomenon taking place in all RO systems. However, a tankless RO system with a smart display panel visualized this process. I have sent you an email explaining the phenomenon. I hope my reply will be helpful to you!
If you have any other questions, please feel free to contact us by replying to this email. I will always be there to provide satisfactory solutions for you.
Enjoy the rest of your day!
Kind Regards
