Our take on the MySmile LP221 Uvc Sterilizable Cordless Water Flossers for Teeth 335ML Portable Oled Display Dental Flosser with 4 Modes 8 Jet Tips and a Storage Pouc White

The MySmile LP221 is a cordless, rechargeable water flosser with a 335 ml reservoir, an OLED display, four cleaning modes and eight jet tips, plus a storage pouch. It is IPX7 waterproof and the tank is designed to be sterilized with UV, which sets it apart from most budget flossers. At $64.99 at Best Buy as of November 7, 2026, it sits at the top of its recent range, so it is not a bargain moment.

Pros
  • 335 ml tank is larger than most cordless flossers, so fewer refills

  • OLED display shows mode and battery status clearly
  • Four modes cover gentle, standard and pulse-style cleaning
  • IPX7 waterproof body is safe to rinse and use in the shower
  • Rechargeable battery rated for about 120 minutes of use

Questions and answers

Is the MySmile LP221 worth $64.99?
It is a fair price for a large-tank flosser with a display and eight tips, but it is at the top of its recent range. If you do not need the big tank or UV sterilization, cheaper cordless flossers do the basic job.
How does it compare with a Waterpik cordless flosser?
The LP221 has a bigger tank and more included tips than most Waterpik cordless models. Waterpik has a longer track record and wider tip availability, while MySmile undercuts it on price.
How long does the battery last?
The battery is rated for about 120 minutes of use, roughly two weeks of once-daily flossing. Heavy use or high modes will drain it faster.
What is in the box?
The flosser, eight jet tips and a storage pouch. A charging cable is included; check the listing for the adapter.
Can the tank really be sterilized?
MySmile says the tank is UV-sterilizable, but there is no independent test data to confirm how much bacteria it removes. Regular rinsing still matters.
When is it cheapest?
Cordless flossers usually drop during Black Friday and Prime Day sales. At $64.99 now, waiting for a holiday sale could save $10 or more.
