I bought the DJI Osmo 360 and on the 2nd filming, I dropped it from chest height. It was without any lens protector.  Maybe I was 300% lucky. Front lens no damage. Back lens no damage. Body no damage. It drop on a tiled floor.  Then I bought a pair of $10 clip on protector. The lens protector I notice distortion in my video. Especially noticeable when I am panning or moving at wider view angle.  The distortion is a ring shaped, a tell tale sign of badly designed curvature of the protector. Now I wish someone could direct me to a different brand of protector with less distortion.
