Thank you for taking the time to share your feedback with us, Shely. We’re sorry to hear that the Oral-B iO Series 7 isn’t providing an efficient cleaning. We’ll share your message with our Quality Team. Our Oral-B iO Series Toothbrushes give an effective clean and the most personalized oral care guidance. The iconic, dentist-inspired, round brush head contours each tooth, while the combination of oscillating rotations and new micro-vibrations gently and more effectively removes plaque along the gumline. Please know that all our power toothbrushes undergo many quality checks to ensure they deliver the best brushing experience. We want to learn more so we can provide you with the best assistance. Please call us at (800) 566-7252.

We always hope consumers will be happy with their purchase, and are sorry to learn your iO 7 is no longer holding a charge. The Lithium-Ion battery should be fully charged in three hours, and that charge can keep your brush ready to go for up to 10 days with regular brushing (2 minutes, twice a day). Individual habits and behaviors may affect that time, but it should still be working. We’re glad you let us know you’re having this concern, so we can further assist you with this. Please have your handle with you, and call us for more help. We’re available Mondays-Fridays, from 9 AM to 6 PM, EST, at 1 (800) 566-7252.

We're surprised and very sorry to hear this. As you have heard from working with our warranty service, our brushes go through extensive quality testing, so this isn't an experience we would expect you to have, especially twice. We'd like to learn more and do our best to make things right. Please give us a call at (800) 566-7252.

Hi, Thank you for leaving this review! We are so happy that you are enjoying keeping track of the 2 min brushing, and are having fun keeping your oral health in check. Thank you, Oral-B
