Great electric toothbrush
I really like my new toothbrush, it seems to do a very good job of cleaning. I’m not sure why when I’m running it that all of a sudden it’ll pause for a second and it will do that as I’m brushing my teeth a few times. That’s puzzling.

Easy to use and fantastic results!
My dentist recommended this electric toothbrush and I can’t be happier. I get the just cleaned feeling every time I use it. It’s easy to use, I love the built in timer, and am amazed at how well it cleans. I use it along with my water flosser and was even praised at my dental office on my oral hygiene! What a wonderful feeling!
Pros
Easy to use, comfortable to hold, built in timer, choice of colors, and most of all, it works wonderfully!
Cons
It does not come with a travel case.
