These units look pretty good. Seem pretty convenient, and it looks like it would be pretty safe too. - no Neck crammps 
I have rear view mirrors (yes they do not get much use at as and they even get in the way - low cost but I kinda wish I only mounted one of them) so I could watch the Rear blower and still keep looking forward.
