We never want you to feel disappointed when investing in a new toothbrush, so we understand how frustrating it is when you can't reach all of your teeth while brushing, and we'd like to help. We carry out extensive research and consumer testing when designing our products. Our toothbrushes are designed to be comfortable and easy to use for a wide variety of consumers. We understand everyone's mouth is different, and preferences vary from person to person, so we greatly appreciate your feedback. So we can learn more about your experience and help you further, please give us a call at 1-800-566-7252, 9 am-6 pm EST, Monday-Friday.

Christian, thank you so much for your feedback. We're incredibly sorry for the confusion and frustration. To answer your questions, this brush has a 24 hours charge time but a 4 week battery life when brushing for 4 minutes a day. The charging light near the on/off switch blinks green while charging. Once fully charged the indicator light turns off. If the battery is running low, the light blinks red after switching the brush off. The three modes for this brush are: Super Sensitive, Gentle, and Daily Clean. You can tell what mode you're on based on the rpm. We'd like to connect about this, ensure your feedback is heard, and answer any other questions you may have. We can be reached at 800-566-7252.

Thank for sharing that you feel our iO Series 2 brush delivers a solid brushing performance. We also appreciate your sharing that you don&#39;t find the different brushing modes make a difference in your brushing experience, and that you find the labeling of our Oral-B replacement brush heads confusing. A lot of thought goes into the design of our products and packaging, to create appealing features, and we offer a range of product versions for the varied needs and preferences of our consumers. Your feedback is important to us, and we’re always glad to help with any questions or concerns. If you&#39;d like to talk more, please give our Oral-B Team a call at 1-800-566-7252 from 9AM -- 6PM EST Monday–Friday.<br />

We're sorry your old toothbrush stopped working, but glad you decided to give the iO series 2 a try. We carry out extensive research and consumer testing when designing our products. Our toothbrushes are also designed to be easy to use for a wide variety of consumers. The iO2 is designed with a low-charge indicator that blinks red after switching off the toothbrush. Your feedback about the location of the pressure sensor is very appreciated, and we're sharing this with our team. In the meantime, we want to let you know that along with the pressure sensor light, the brush will slow down, and there will be a noticeable change in sound when too much pressure is applied. Your satisfaction means the world to us, and we'd like to learn more about your experience with your iO2. To share more, please give us a call at 1-800-566-7252, 9 am-6 pm EST, Monday-Friday.

Thank you for your feedback. We’re sorry to hear that you’re unhappy with the features of your brush. Please be assured that our products undergo many quality checks and testing to ensure they arrive in perfect condition and are something you’ll enjoy. The brush head bristles can wear faster by applying too much pressure, rinsing a toothbrush under hot water, or soaking it in a solution. Your feedback is helpful, and we’d like to hear more. When you’re able, please call us at (800) 566-7252 so we can assist you further.
