I was very skeptical on these sunglasses due to the price, but was recommended on a different site so I took a risk and bought a pair. I've had a similar pair of RayBan's for the last couple years and these were way more comfortable and the polarized lenses are a game changer.  They feel well made and are not like those cheap disposable sunglasses.  I see clearly with these and the colors really do pop rather than just a grey shade on your eyes.  I liked them so much, I bought a 2nd pair just to have around in case I lose these.
