I've had prop guards since the day I got my V1.1.1, 2014, and felt very happy with them especially as I Hand catch, but yesterday I was flying fpv with the wife as spotter, it was a bit gusty at the time and suddenly there was a zzzzzzzziiiiiiiippppppppp, I knew what the sound was, a prop hitting the guard,maybe about a dozen clips as I was turning left,not sure if it was the prop dropping down or the guard being blown up,or a bit of both, stationary there's a 1/2" gap between the two.
I didn't notice it with my fat shark goggles as the gimbal was doing it's job, but the sound from the ground was loud enough to make me land right away
the thought of a prop breaking has now made me takeoff the guards but I'll have to be more careful with my hand catching.
I'm also a believer in the prop guard fixing under the motors being a help to stiffen the motor mount hopefully to avoid cracking on the mount so my spare set of slightly marked prop guards I've cut the guards down to only the center boss and screwed them back on
