The water tastes clean and fresh, and it’s easy to install and maintain.After using this a few times, I noticed water dripping a little bit from the faucet tip. Except for that this works great. Recently for some reason, the machine stoped working. When I contacted customer service, they, especially Becky solved the problem in a timely manner. I was so impressed by her effort and service. Highly recommend!! ### ⭐⭐⭐⭐⭐ Excellent unit! *by on Reviewed in the United States December 24, 2025* We just got this hooked up and so far it seems amazing! Was really easy to setup and get started. Changing out the filter also is a very simple process. It holds a lot of water, which is great. The water comes out pretty quick compared to other filtering units. We have a jug we fill up and then put in fridge for cold water. The hot water feature on this is incredible, comes out immediately without having to wait for the temperature to change. Hot enough for a cup of tea. Water is crystal clear and tastes great. For anyone living in an area where you can not put one under the sink, this is a great option. Also, looks very stylish and clean on the counter. ### ⭐ Malfunction after a month of use *by on Reviewed in the United States July 4, 2026* Don’t buy it. Malfunction slightly after one month (also the return window). Have been using it normally, following the instructions. Reached out to CS and ruled out factors but still not working… ## Frequently Bought Together - 【Instant Hot】 Waterdrop K19-H Countertop Reverse Osmosis System, Reverse Osmosis Water Filter Countertop, 3:1 Pure to Drain, 4 Temperature Options Water Dispenser, No Installation - Waterdrop WD-K19RF Filter, Replacement for WD-K19-S and WD-K19-H Countertop Reverse Osmosis System, 12-month Lifetime - 2024 All-New 4 in 1 Tds Meter Digital Water Tester - Accurate and Reliable TDS EC & Temp(°C,°F) Meter - 0-9990ppm - Professional Testing for Drinking Water, RO/DI System, Aquariums etc --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sc/products/627827679-waterdrop-k19-h-instant-hot-countertop-ro-system-no-installation](https://www.desertcart.sc/products/627827679-waterdrop-k19-h-instant-hot-countertop-ro-system-no-installation) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-08-21*
