Good comfortable fit with no slipping. Impressed with the construction, haven't seen the auto tint in action yet as since they arrived the sun has dissapeared. Only reason i have given fours stars as I am yet to test them properly.
I purchased both Falcon & Music Shield. They've become my new dailies. I have a huge collection of sunglasses and so far, these 2 pairs are my favorite to wear. I love my Chamelo sunnies!!
I have the Dusk sunglasses and discovered how often you need to adjust the tint while turning into shadow with both hands on the bars.. (more than you think!) These glasses resolve this potentially hazardous situation..
