Ive only had these a couple days but I must say my initial impression is that they are awesome. I have a LARGE head and these things fit perfectly. I had to do a little adjusting of the nose pieces but thats to be expected. I actually just purchased a second pair as Im pretty hard on glasses while working. Now I can have a pair to keep in my personal truck thatll not be treated as roughly. Ill update this review as necessary but so far they are great glasses at double the price...they are amazing glasses at the current price. Update, Im almost 3 months in and they are still going strong. I have to be honest, Id be ok replacing these every three months, for the price. So far so good though.
