The Olfi Suction cup is ideal for using on any flat surface like a normal, big and clunky suction cup but is twice as strong! Uniquely, this suction cup can be attached to a curved surface like a helmet, ski, bike or car body. Even if the surface is slightly rough, the soft jelly rubber padding will block up any small gaps and create a secure seal. This rubber padding also helps dampen vibration found in high speed activities. This really is the must have mount for everyone in every sport.
