Great for use everyday. Simple enough to operate perhaps a 3 second difference between opening regular sunglasses. I have gotten so many compliments, and just for the look, only two have seen the transition and commented. My only gripe is the case it comes with does not protect/clean the lenses. I have tiny scratches on the lenses caused by the dust embedded in the rubber of the case. I emailed them about it and they said I could buy a different case...for 30USD...I didn't feel like they understood the problem and did literally nothing to make it right (other than pitch another sale). Despite this, I love the glasses and will recommend them.
