Go Moto is not responsible for any damage caused by improper installation. The fitment of the Go Moto Mount has been tested thoroughly on all different helmets and on different helmet sizes. The Go Moto mount comes with an original 3M VHB adhesive and is able to hold a great amount of force. Only extreme situations like a crash could be the cause of your mount coming off your helmet, or improper installation. Read the manual on how to install the Go Moto mount and always use the provided 3M VHB Surface cleaner for optimal adhesion!
