Anyone use a heated face shield? I have a bad time with fogging my shield and getting frost to the point where I can't ride with the shield down. I don't want to chose between seeing and keeping icicles off of my eyebrows (froze 'em up today!). I have a HJC CL-12s (according to the box) that I picked up few years ago. I've tried anti-fog wipes, and they didn't do the trick. So I'm looking at a heated shield, what's the cost? How hard are they to install (plug into sled)? Where to I hook the wires up to for power? Thanks, any input is appreciated!
