The Oral B Cross Action Power Battery Toothbrush has been a great addition to my morning and bedtime routine. I have only had it for a couple of weeks, so I cannot attest to its durability or longevity (no idea how long it will take for the battery to die or when I'll have to get a replacement head), but so far, I've been really impressed with the job it has done cleaning my teeth. I have very closely spaced teeth and my back teeth are nearly impossible to brush with a manual toothbrush because they're so far back in my mouth, but having the power toothbrush makes it easier to get it clean back there with the vibrating and spinning motion of the bristles. I feel like my teeth appear whiter and there's definitely that "just-got-back-from-the-dentist" feeling of slick teeth after brushing. The price on these toothbrushes is also very reasonable and from a trusted brand like Oral B, I believe it to be a well-made product. I would add that the vibrating feeling is a bit strange to get used to at first. And my husband is still not convinced he likes it, so it might not be for everybody, but I've enjoyed my introduction to this toothbrush.
