text: I bought these as a replacement for my Spy Optic Diablo sunglasses, they are only slightly bigger in the frame, and I am not a fan of the BUG EYE look that most sunglasses are pushing toward. I have worn these glasses for over a week now and there is one major difference, there is no rubber on the ear piece. Seems simple to me now, but it makes a BIG difference for every day functionality. I usually place my sunglasses up on the top of my head when I walk in to a building, makes them easy to keep track of and they are ready when I walk back outside again. However because there is no rubber to aid the grip on these glasses, any time I move my head to look down or around they want to fly from their placement. The last thing you want to do is drop your nice sunglasses, risking damage to the lenses or breaking the frame. I am actually pretty disappointed with these as a result of this design change.
