Very good when walking around town to check if pretty girls are looking at you ;) The lens look fragile and they feel a bit tight on the head.

The design of the glasses is very nice, and I like that the lenses are flat. They do what they advertise, I can really se behind me, but at a slight angle. For example, if I seat in the drivers seat, in a car, I can see the person on the righ back seat For the price they sell, I relly have no complaints. When they arrived, one of the lenses was chipped,... Read more

They look cool and are comfortable to wear. The side mirror thing works like a charm too. They are very fragile and therefore must be treated extremely carefully. But well, same goes with almost every sunglasses. The lenses are little bit too big for me but that's just a personal preference. I originally bought them mostly for the Anti-Track feature ...

Excellent idea, perfect for people who like gadgets and its unlikely that they already have a pair or know about them.
Strong, well made and very good buy.
Looks like normal sunglasses; even when up close, so only the wearer knows they show two directions. Very masculine looking - although my sister liked them purely for the novelty appeal.

Good points, good sun protection. Pleasant look on his face. Build quality is very good. Superb carrying case.
Bought them for cycling, used instead of mirrors))) Strong glare when the sun is shining from behind, very uncomfortable. After some time, erased mirror coating.
A bit too small. If they were bigger, it would be much better. Great toy, you ... Read more

Use the protective case, because it´s a bit sensitive to scratches and stuff.
