Powerful cleaning
I got this to prevent gum recession and enamel erosion while keeping teeth clean and preventing gum disease. Also, it makes sense (though I'm not a dentist) that the sonic vibrations (like a massage) may help heal tooth ligaments that get irritated from orthodontics, clenching, impact, biting on hard things, etc. This model makes a different sound when you press too hard, but that different sound is not quite different enough so it is hard to tell whether I am in fact brushing too hard. Mine came with an InterCare brush head, which was very stiff and irritated my gums. I replaced it with the Sensitive head, but sometimes the bristles are too soft and bend so much that the brush head hits my teeth (which acts better than the sensor as protection from brushing too hard). It makes a strange sound and feeling when the brush head hits my teeth, but nothing has been chipped or broken and the brush is much more lightweight than other electric toothbrushes on the market that use AA batteries, so I think it is safer to accidentally hit teeth with this than with others. Performance/Cleaning Even on the lowest setting, my teeth feel very clean. The front teeth are a bit hard to brush, especially without spraying toothpaste around. Durability Very durable. It holds a charge very well for traveling. I have also dropped it on concrete and had the plastic on the bottom get a bit roughed up but it still works great. It says that baking soda and peroxide toothpaste can damage the handle but I have seen no evidence of that, even though I use that toothpaste and do not clean the handle after each use.
