Feiyu FY-G4 3-Axis Handheld Steady Gimbal Test

Looks good as far as stabilization but what happens at hwy speeds? What if it rains? Why not make a proper helmet version instead of a handheld strapped to a helmet. Chin mount that gimbal. How much? The last one was too much. These things have to be under $200 for it to sell by the masses and have the ability to hold other cameras and phones.
