Next time you design something like the 10C for which, to use, one needs a clean lense in driving direction, please add a loop or hole to the device as well as the lense protector, so that we could drive with the protector on and remove it directly prior to using (and, optimally, put it back on afterwards), so that no flies can impact into the lense (and render the camera worthless for that ride) while it's not necessary.

Or make the protector a "flip up" plastic lid or such (or "flip down" or wherever).
