We're sorry to hear that your iO Series 5 brush is no longer charging, Sophy, as we have strict quality checks in place to ensure that you can rely on our products. If you haven't already, we suggest making sure your brush isn't being charged near any metallic surfaces, and we also recommend giving another outlet a try. As well, try fulling charging your brush for 12-24 hours. We hope these tips are helpful, and please give us a call at (800) 566-7252 if you'd like any further assistance with this.
