Amazon's most-rated electric toothbrush comes with 8 heads, a travel case and a month-plus battery. Testers found it feels cheaper and less gentle than Sonicare or Oral-B, and it has no pressure sensor.

Top complaints

  • Intense vibration, not very gentle

    Electric Teeth found it less gentle than Sonicare or Oral-B, said even the soft mode didn't feel very soft, and described the bristles as stiff. Amazon's summary calls the vibration level mixed and pretty intense. Some 1-star Walmart reviews say the vibration was hard to tolerate.

  • No pressure sensor

    CNN Underscored says the missing pressure sensor is the main reason it didn't earn a top spot. Electric Teeth also lists it as a con.

  • Cheaper build; some die around 6 months

    Electric Teeth says it feels cheaper than premium rivals (the chrome rings are plastic) and notes some reports of breakage; the warranty is 1 year. Amazon's summary says durability is mixed, with some owners saying it stopped working after 6 months. Walmart low-star reviews mention dead chargers and heads that don't stay on.

  • Small heads

    CNN Underscored notes the included heads are on the smaller side, and a Walmart 1-star reviewer compared the head to a toddler's.

What experts say

  • CNN Underscored: Tested but not picked: a great affordable option with four modes and a travel case, held back mainly by the lack of a pressure sensor.
  • Electric Teeth: 4.4/5 and excellent budget value. The cons are no pressure sensor and cheap materials, and it is less gentle than Sonicare or Oral-B (65 dB).

If that catch is a deal-breaker

Highly ranked electric toothbrushes whose biggest complaint is something else.

#1 in electric toothbrushesOral-B Pro 1000 Rechargeable Electric Toothbrush

Wirecutter's long-running top pick, with cheap, widely available heads. It is louder than sonic brushes, and its pressure alert is easy to miss. Owners also report units that stop holding a charge.

Its catch: stops holding a charge or dies early#3 in electric toothbrushesPhilips Sonicare 4100 Rechargeable Electric Toothbrush

A quiet, simple sonic brush that two major testers rank first or second, but its heads cost about twice as much as Oral-B's. Owners also report units that stop charging or die within a year.

Its catch: heads cost about twice as much as oral-b's#4 in electric toothbrushesOral-B iO Series 9 Rechargeable Electric Toothbrush

CNN's favorite smart brush, with seven modes, a color screen and app coaching. It costs about $300, uses pricier iO-only heads, and testers disagree on how accurate its tracking is. Its battery is shorter than many cheaper brushes.

Its catch: very expensive
