I had been using basic Oral B powered toothbrushes from the drugstore for a while, and started considering a sonic style line instead. I had looked at all of the sonicare models and couldn't pick one out, so I stopped looking. I quite literally stumbled upon this, while looking for a foreo face brush, and was instantly intrigued. I have sensitive teeth and gums with weak enamel and am prone to cavities, so it's important for me to keep my teeth very clean without overbrushing, and this product does just that. Aside from its toothbrushing performance, there are so many pros about this: a single charge lasts for 1 year!, brush heads only have to be replaced every 6 months, the brush comes with its own leather travel slip, and a slim charging cable.
