We're so sorry this happened to you. The brush has a built in feature to cancel this 'wake' function if it is activated several times in a row without the power being turned on. The process of wake and sleep is not considered to cause a significant drain on the battery. Since this isn't something we'd expect to happen, we'd like to learn more about your experience for our Quality Teams. When you get a moment, please phone us at (800) 566-7252.

We're disappointed to hear your iO7 is no longer working. With the many quality tests that these brushes have gone through, we expect them to give your smile a great clean for many years. Our team would like to see how we can assist you with submitting your brush via our 2 Year Manufacturer Warranty. When you have a chance, please 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.
