These glasses for the price are worth it. I got the colors that were represented in the picture. The dizziness that some other people mentioned, goes away. They are pretty small but since my head is pretty small--it worked fine for me. They are by no means qood quality. They are made of PLASTIC and SCRATCH easily. Once they are on the ground and get pushed around especially on gravel, cement, etc--they become unusable unless you like looking through scratch marks. I mainly use them when I'm driving. I wouldn't give them as gifts, since they are very cheapy. The lenses can be easily taken out and put back in.  If you want something to wear to concert, these work especially if you are worried about loosing them. I still have all of mine, though the green glasses are scratched.
