A popular Amazon budget flosser that Electric Teeth couldn't tell apart from pricier brands in a blindfolded test. Expert coverage is thin, the warranty is only a year, and owners report charging failures and mixed pressure.

Top complaints

  • Stops charging or dies within a year

    Amazon's review summary says battery feedback is mixed, with some owners reporting it stopped charging after one month, and that units break after a year. Electric Teeth raises reliability concerns because it is a newer brand with a 1-year warranty.

  • Pressure too low for some

    Amazon's summary says power and water pressure get mixed reviews, with some owners finding the pressure low.

  • Barrel-pin charger, no case, awkward nozzle

    Electric Teeth says the barrel-pin charger is less convenient than USB-C, there's no travel case, and the nozzle is harder to hold and rotate one-handed than on the Waterpik Cordless Advanced.

What owners love

Good for
  • Tight budgets
  • Lots of spare nozzles in the box
  • Trying water flossing before spending more

Scores (tap for why)

What experts say

  • Electric Teeth: Best budget pick ($33.99): performs on par with pricier brands, but has a 1-year warranty, a barrel-pin charger and no travel case, and it feels less premium.
