## Description

Waterdrop C1SL Mineral Reverse Osmosis System, 7-Stage Countertop Reverse Osmosis Water Filter - desertcart.com

Review: Great customer service - I have to give a big shoutout to the Waterdrop team. The first system that I bought, it stopped working after 6 months. I was extremely disappointed and reached out to the Waterdrop team because 6mos for an osmosis system seemed unacceptable. Kimberly helped me out the entire time; she was able to order a new one for me without any charge! Since then, the machine has been working beautifully. It has been almost a year. For the price, you're getting good quality. It's easy to use, water tastes good, and the filter is still at 60% after about 5-6 months of use. Kimberly checked in again via email, months later to make sure the machine was working. I truly appreciate the amazing customer service and how Waterdrop stands by their products. Thank you! Highly recommended.
Review: Waterdrop Truly Cares About Its Customers - I bought the Waterdrop countertop system about 2.5 years ago since installing an under-sink unit wasn’t possible in my home. Overall, I was very satisfied, but at one point the water tank started leaking after 1.5 years. When I contacted customer service, they quickly replaced it with a new one without any cost. Recently, the old unit stopped working unfortunately, so I decided to look for a replacement. The new upgraded model is even better—sleeker design, improved features, and it works perfectly. Thanks to Olivia from customer service, I was able to take advantage of a great Labor Day Sale deal. She was very helpful and supportive throughout the process. I also love that the new system now uses just one filter instead of two, and the filter life is longer, which makes maintenance easier and more affordable. The water also tastes even better now, which is a great improvement. Highly recommend both the product and the outstanding customer service!

### ⭐⭐⭐⭐⭐ Super Customer Service & great product
*by C***N on March 26, 2026*

I bought this Waterdrop CoreRO in Jan 2026. Unfortunately some sensors were not working well and it was impossible to install. I wrote to the seller Representative Ms Becky and after checking out with their technician they decided to replace the unit. Within few days I received the new Water Filter RO. Ms Becky was always in touch with me to make sure that this time all is fine. I am happy with the Waterdrop CoreRO and recommend it highly. On top of that I want to thank the Waterdrop company especially Ms Becky for their great customer service and continuous support. Ms Becky with her team is the Super Customer Service Rep 🏆
