Hello sgande, We're delighted to hear that you like the brush, and sorry that you are having an issue connecting to our app. We want to help! We recommend making sure that you update to the latest version of the Oral-B App, version 8.0.3! It's also important to make sure that your location settings are turned on (if you have an android phone) and to make sure you aren't connected to any other Bluetooth devices for the best connection. We hope this helps! Please feel free to contact us directly if you need further assistance. You can reach us at 1-800-56-ORALB (800-566-7252) M-F 9-6pm EST. Happy Brushing! Your Friends at Oral-B

Maintaining a healthy smile is so important to us, Emmie, so we're very sorry to hear that your brush is no longer spinning. If you have not done so already, please try removing the brush head and rinse the parts under warm running water. There may be hardened toothpaste preventing the brush from moving as expected. We'd love to learn more about this and help you with your iO Series 9. Please call us at (800) 566-7252.

The Oral-B iO 9 should last between 7-14 days on a single charge depending on your brushing habits. If you brush for the dentist-recommended two minutes, twice a day you should get at least 10 days from a single charge, but brushing more often will mean you’ll also need to charge the handle more often. It still doesn’t sound like you’re getting the battery life we expect, however, and we’d like to learn more about what’s going on so we can help. Please know all of our rechargeable electric toothbrushes come with a manufacturer’s warranty against defects. Give us a call at (800) 566-7252 and we’d be happy to assist you.

As you can imagine, this isn't the experience we expect you to have with your brand new Oral-B iO, Pam. This is likely because it got into contact with an ingredient that is corrosive in nature and made the plastic porous. These things are found in things like soaps, cosmetics, and cleaning agents. You can clean the brush after each use and store the brush head and brush handle in a well ventilated and it should prevent this from happening in the future. For further assistance, please contact us by dialing (800) 566-7252.

When brushing 4 minutes a day, we expect your iO Series 7 to last around 2 weeks. We're sorry it's not lasting as long as you had expected. Please charge the brush for 24 hours, discharge it completely, fully charge the brush again, and repeat 2-3 more times. This may help improvise the battery performance, but we'd like to hear from you about this and help some more. Please call us at (800) 566-7252.

We want you to be blown away with the amazing cleaning performance of our iO series 9 brushes, so we're so sorry to hear this wasn't your experience. We want our brushes to last for many years after rigorous quality testing which we stand behind with our Oral-B Money Back Guarantee, so we'd love to learn more. When you have a moment, we hope you'll give us a call at (800) 566-7252.

We're sorry to hear about your most recent experience with your purchase. Our brushes go through many tests so that they work the best for you. Please give us a call at (800) 566-7252 so that we can help check on the status of your repair.
