Review: Cenoire Eluo Sonic Toothbrush

Cenoire sent over its Eluo Sonic Toothbrush, for some reason. It's compact, looks like a candy cane-colored mascara stick, and vibrates.

Powered by one AAA battery, it has a proper on-off button to prevent accidental activation, a replaceable brush head, and claims 23,000 strokes per minute. In use, unfortunately, it's clearly not the same breed of gadget as leading-brand electric toothbrushes. The movement, while fast, is so delicate and underpowered that one hardly feels like a good job is being done.

I am no dentist, but even slight hand movements, while gripping it, provide much more friction than the vibrations of the head. One is tempted to use it just like a standard toothbrush.

It is very pretty, though. And I feel pretty for having used it.

  1. I have one of the cheaper sonicare brushes ($25) and I never felt like it was doing anything but making noise. I suppose I was taken in by the hype. I half expected the brush to simply blast the plaque off my teeth, leaving me with JJ Abrams lens flares each time I smiled.

    1.  Be careful.  It may not feel like it’s doing much but at that vibration rate it can do a fair amount of damage if you start using it like a regular toothbrush on top of the action it is already providing.

      I went from a regular toothbrush to one of the pricey Sonicaires and my hygienist noticed the improvement of gum health on my very first return visit.  (Note that I did not buy the Sonicaire from my dentist).

  2. A pet peeve is anything powered by AAAs. They have 1/3 the energy at twice the price. That makes them six times as expensive per kWh. Usually there is enough space for an AA. And 23,000 strokes per minute sounds a lot more impressive than 383 strokes per second (would they tell you a car engine runs at 360,000 revs an hour?)
