I generally don't like to leave bad reviews, but these are worth it.<br /><br />Two strikes on zeroUV.  The first pair I ordered, I received the package for the glasses and the carrying pouch.  No glasses to be found.  Called up Amazon, they gave me a refund, no big deal.  Sure I was disappointed, but it happens.  At least they believed me and gave my money back.<br /><br />I gave them the benefit of the doubt, and reordered the sunglasses.  I really liked these glasses for the week that they lasted.  I even had a coworker ask if they were RayBans.  They look great, they are comfortable, and are actually polarized.  However, DO NOT leave them in a hot car.  After leaving them in my car on a single 90 degree day, they plastic became weak enough that one side broke off simply from the force of opening them.  At first I thought that I was the one that broke them when I put them away, so I was just mad at myself and glued them back together.  However, the next day (also 90 degrees), BOTH sides broke when I opened them up.  They didn't snap or anything, I just opened them and they split, with literally just the force of opening the glasses.  They are now being held together with superglue.  Hopefully that holds up long enough for my new glasses to come in.  I learned my lesson, and this time I didn't buy from zeroUV.<br /><br />I would try getting a refund on these too, but I feel like I would look suspicious getting two refunds on the same item within just a few weeks.
