The sonicare flexcare 900 series electric toothbrush was a gift to me a few months ago. i was little over excited to recieve it, and started using it immediately. i love the deep clean it provides, and how i have to do hardly any work even though my mouth is cleaner than with a manual brush. my favorite feature on this toothbrush is that is has several different modes, one of which is a quick mode. in the morning i'm always rushing and love that there is a mode just for that! it's about 2 minutes, and beeps every 30 seconds to switch sections of my mouth. it keeps me on track with my oral hygiene...
