Top complaints
Oral-B iO Series 9 Rechargeable Electric Toothbrush
- Very expensive
CNN Underscored calls the roughly $330 list price a tough sell even on discount. Electric Teeth puts the US suggested price at $299.99. Amazon's summary says value for money is mixed, with some owners finding it overpriced.
- iO-only heads and a mold-prone gap
Electric Teeth puts iO heads at about $8, roughly twice the price of standard Oral-B heads, and says mold can build up in the gap around the magnetic head mount. Wirecutter notes some customer reviewers clean that junction daily.
Source: Electric Teeth, Wirecutter - Tracking accuracy disputed
Electric Teeth found position tracking inconsistent, sometimes logging the wrong zone, and worse for left-handed users. CNN Underscored, by contrast, found the app accurate every time it tested it. Amazon's summary calls tracking mixed.
- About 12 days per charge
Electric Teeth usually got about 12 days against a 14-day claim, though the charger refills it in about 3 hours. Amazon's summary says some owners report it doesn't hold a charge.
Oral-B Pro 1000 Rechargeable Electric Toothbrush
- Stops holding a charge or dies early
Amazon's review summary says the battery gets mixed feedback, with some owners saying it stops holding a charge and several saying it stopped working within two weeks. Walmart's lowest-rated reviews describe units that stopped charging after about two months, chargers that didn't work, and a motor that slowed down after a month.
- Loud
Wirecutter calls Oral-B brushes like the Pro 1000 louder and more sonically grating than comparable Sonicare models. Electric Teeth measured 73 dB, versus 60 dB for the Sonicare 4100. Amazon's summary says customers find it somewhat loud.
- Weak pressure alert, no auto shut-off, vague battery light
Wirecutter's testers had to press harder than expected to trigger the pressure sensor. The brush also keeps running after two minutes until you switch it off, and the battery light only shows full or low. Electric Teeth found the pressure alert neither visible nor audible and easy to miss.
Source: Wirecutter, Electric Teeth - Button and slippery handle
Amazon's summary says some customers struggle with the on/off button. Walmart low-star reviewers say the button is hard to use and the smooth plastic body gets slippery when wet.
