I liked the idea of folding sunglasses. The form factor was great. The included carrying case was perfect for throwing in a bag or in my car.
The style was a bit more european than my normal taste. But, not too bizarre.
However, the glasses weren't as wide as I'd like and the arms weren't as long as i'd like.
My biggest knock though, is the durability, the number one quality a cheap pair of banger glasses needs is resilience. One drop from waist height took these dudes down. Split, irreparably on the nose.
