Touch and reliable design

Sumo DM is built to withstand a child’s rough-and-tumble lifestyle. The interior components are well protected in order to avoid moisture-related breakdowns.

Sumo DM’s Battery Management System ensures consistent output performance, warning the child and caregiver with “battery low” beeps and by turning the status light off. This system functions with any 675 zinc-air batteries, although dedicated power batteries may ensure better performance.
