I wanted to love these so badly. They're stylish and dramatic and even the case is cute. However, the first pair I received was severely warped - the left lens was bent in towards your face. I figured it was just a lemon so I sent them back and got a replacement. Wouldn't you know, the second pair had the same problem (to a lesser degree but still noticeable) AND the arms were extremely tight. They do come with instructions for heating and adjusting the arms but it was all in poorly drawn pictures - not very helpful! Bottom line, these glasses are not worth the hassle, especially for the price.
