Great product

[This review was collected as part of a promotion.] I have been a longtime fan of all things Phillips. My latest purchase of the Diamond Clean toothbrush has taken me to a new level of appreciation. It's a little pricey but it's worth every cent. Every time I use it I feel like I've just been to the dentist for a cleaning.

So far so good

[This review was collected as part of a promotion.] This replaced my old Diamond Clean 9000 and, so far so good. I find it to be better built and identical. I am not certain if I can appreciate significant difference otherwise, so can't tell if paying significantly more for this one is justified. All in all, this is a great product and hopefully lasts me a long time! I can see how the charging travel case is a neat update for those traveling often. For what it's worth, my dentist's office are happy with the quality of my hygiene!
