(checked 2026-10-10)This Amazon listing is titled 'Sonic-Fusion ... SF-04' without '2.0'. Electric Teeth calls the SF-04 the Professional version of the 2.0.
A popular two-in-one sonic brush and water flosser with a 3-year warranty, but expert testers prefer separate devices. Its heads cost over $12 each, the brush battery is short, and owners report the flosser or whole unit failing.
Top complaints
- Unit or flosser stops working
Amazon's summary flags durability, citing units breaking after 3 months, and says flossing performance is mixed. Walmart 1-star reviews describe units dead on arrival, flossers that quit within weeks, and a casing that fell apart.
- Most expensive heads here
Wirecutter says replacement heads cost over $12 each, among the most expensive it considered. Electric Teeth found them at $25 for two.
Source: Wirecutter, Electric Teeth - Clunky, corded and not portable
Electric Teeth calls it conceptually great but poorly executed: the handle is chunky and heavy and the flosser base isn't portable. Walmart reviewers dislike the cord running to the sink and call it clunky and loud.
- Short brush battery
Electric Teeth measured about 11 days on the higher speed, short of Waterpik's roughly 2-week claim, and lists poor battery life as a con.

What owners love
- Feels very clean
Amazon shoppers call it easy to use and say it leaves teeth feeling super clean.
- Long warranty, ADA accepted
Electric Teeth notes a 3-year warranty and ADA acceptance; Waterpik's replies to Walmart reviews cite the same three-year warranty.
- Adjustable flossing pressure
Electric Teeth notes 10 pressure settings and a timer and pacer.

What experts say
- Wirecutter (NYT): Not recommended: Wirecutter found separate devices work better, and the heads cost over $12 each.
- Electric Teeth: 3/5: most people are better served by separate devices. Cons are poor brush battery, a non-portable flosser and one tip style; it measured 71 dB brushing and 80 dB flossing.
