Those who are considering travel toothbrush like One by Sonicare, this is slightly bigger than One.
1 inch diameter. not bad as a travel toothbrush.

You're right...I saw "battery operated" and didn't read all the details. Sorry. Worth a shot for $3.99 then. Smilie

Used mine today, I got 2 for $10 last week.

Not nearly as nice as my sonicare, but good enough for my backpack and gym bag.

Considering it comes with replacement heads, it's cheaper than a regular toothbrush

High pitched noise. If you don't already have tinnitus you soon will.

Scored one last sale. Tried and it is better than the Optimal Clean Sonicare I bought from Costco.

No, just the usual 'dominate, destroy competitors, and make them reliant on china' plan that has worked to destroy other industries.
