Advantage of the GUM Smart One subscription:
You conveniently receive a double pack of brush heads delivered to your home every 6 months — with no shipping costs.
Do I need a subscription to use the GUM Smart One?
With the basic version (without a subscription), you not only get a super-smart sonic toothbrush, but also access to detailed brushing evaluations, interactive coaching features, and the quiz game in the app — helping you discover areas for improvement and achieve even better results.
Of course, the GUM Smart One is a highly innovative and fully functional electric sonic toothbrush, even without a subscription.
How can I cancel my subscription?
You can cancel your subscription at anytime by writing to help@sunstargum.com
