Another quality Autel product! Where my bird is often flying 'Up close and personal' to houses, trees and other drone eating objects, prop guards seemed like a good investment. I was overly impressed with the EVO prop guards from Autel. Not flimsy junk! Autel has provided some very rugged prop guards, constructed with a very durable and flexible material. The little bird looks and is a lot bigger with these guards, but field testing has already reaped benefits in getting close up details of roofs. I have no relationship with Autel, just a huge fan of the thought they put into this great little bird and their accessories.
