this is my fifth electric pair and all has been great, uses them a lot and no one has been scratched or been destroyed. this pair is great for use on cloudy or at night(i wear sunglasses all the time) olso great in the day but as the lenses are graded they dont block the sunlight as a regular gray or brown lens. the bsg is fantastic for everyone who is active. i have glasses from meny other brand, as anarchy, oakley, spy, gucci, armani and nike and i have to be really careful with those, but with my electric i dont hacve to give a shit as they just dont break. one pair(charge) i lost down a flight of stairs, about 5 stories, bang into edges allthe way down, and all that happend was a scratch on the part over the ear, dont think, just buy elctric and you are set.
