Vestaboard is designed for daily on going use in home and in commercial settings. As a physical product, it is subject to interference from third parties such as curious adults, children and animals, and you are responsible for preventing interference in private or public spaces. Physical interference is not covered by warranty. Vestaboard may occasionally benefit from dusting. Should a Vestaboard Bit (or character unit) ever require replacement, the frame and mask is removable and power is discontinued so that you can easily replace.
