compared this to the poshei 03 and the rivbos 801. i expected this to be a higher quality plastic, because all they give you is a microfiber bag and the pair of sunglasses.  no extra lens or anything.<br /><br />when I took it out of the bag, the plastic frame just felt horrible.  extremely flimsy.  the hinges felt weak.  the lens was loose, like it could fall out at any second.  The only redeeming feature, was the bag, which felt... nicer than the others.<br /><br />in comparison, both the poshei/rivbos felt higher in quality, slightly tighter hingers and sturdier plastic and a better hold on the lens.  possible that I got a bad one, but I'd definitely compare to the others before going with this one, especially since this is the most expensive of the three i bought.
