Electronic toothbrush is designed for adults. The toothbrush has a high-frequency, powerful vibrating motor. It is fully washable and water resistant. The toothbrush gets into hard-to-reach places and achieves a more efficient cleaning effect than a conventional toothbrush. It also provides a built-in, durable display on the handle that provides an overview of important information. The toothbrush can be charged in two hours and lasts up to 20 days on a single charge!
