Review (5/5): Best toothbrush ever!
Great replacement toothbrush for an older model sonic that was left behind on a trip. The longer, more narrow brush head is great. After trying the e5500, was glad to have lost my other sonic! The carrying case is an added bonus! I love the 30 second timer as it ensures I brush evenly (and long enough!). My dentist loves that I use the sonic, as well!
