Review: Great looking gadget that does what needed - Great item with a lot of power. We bought this one after our old one stopped working. I would say it is on the expensive side, but considering functionality and the attachments it's what you would expect. I really like the screen that actually shows the mode you are using, battery left and even water temperature. Though I did find the battery display to be no accurate and not sure about the water temperature. It would show 15-10% battery left and then just shut down. Also did not manage to change the temperature display from F to C. I followed the instructions, but no luck. Might be I did something wrong. A great feature is UV that you can turn after every usage. Water capacity is what you would expect and it last about 1-2 min while using it. I would strongly suggest to to register it for warranty as our first one broke down only after 4 months (screen stopped working). I could still use it, but it made it a lot harder. Since I had the warranty after a couple of emails back and forth they send me a replacement. Review: Great product - I’ve purchased this product on 13 November 2025. I use it daily for minim 2 minutes. I have still not charge it again after a full charge to this day when i write this review - 01 April 2026. One of the best products i ever had.

Thank you! ### ⭐⭐⭐⭐ Good product, but of limited actual dental value *by M***E on 3 March 2025* I bought this based off all the hype and how it was "better than flossing" etc. Turns out it isn't. The product itself is great. Works fine, good display, including remaining battery life. Doesn't lose its charge when not in use for longer periods. Loads of settings for different water strengths. Feels a bit weird at first when you shower half the bathroom in water because you haven't got used to using it, but you soon get the hang of it. It's a good idea to use warmer water if you have sensitive teeth, otherwise you'll be taking a trip to Paintown. But as an actual flosser, it doesn't do much. It just squirts water round your mouth, which is useful for dislodging small food particles but it doesn't get all of them or even close. My dentist said it's better than nothing, but it does less than a packet of interdental brushes, which cost three quid from any chemist. So a really nice product in itself, but it's not a substitute for flossing. ## Frequently Bought Together - MySmile LP221 UVC Sterilizable Cordless Water Flossers for Teeth 335ML Portable OLED Display Dental Flosser with 4 Modes 8 Jet Tips and a Storage Pouch for Home and Travel (Midnight Black) - Aquasonic Black Series Ultra Whitening Toothbrush – ADA Accepted Electric Toothbrush- 8 Brush Heads & Travel Case – 40,000 VPM Electric Motor & Wireless Charging - 4 Modes w Smart Timer --- ## 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.vn/products/596722978-mysmile-lp221-uvc-sterilizable-cordless-water-flossers-for-teeth-335ml](https://www.desertcart.vn/products/596722978-mysmile-lp221-uvc-sterilizable-cordless-water-flossers-for-teeth-335ml) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-19*
