I received these sunglasses on Friday 7/24 & immediately fell in love w/ them!!  I noticed right away that this pair felt much sturdier than the el-cheapo sunglasses I usually buy.  I frequently push my sunglasses up like a headband & I really liked the springs in the hinges on this pair. The way the springs are made to flex outward a tiny bit (instead of just inward to the folded-up position) made these fit extremely well even when I had them pushed back.<br /><br />But on the very first night, I began to notice that the left side would no longer fold up properly. I thought it was simply a loose screw & had planned to tighten it w/ an eyeglass repair kit. But before I even had a chance... Sat morning 7/25, the plastic arm on the left side completely separated from the metal hinge (as shown in the photos I added to this review). I may still try to superglue the metal hinge piece back into the plastic arm. But the hinge is sooo tiny that I'm concerned I'll miss & may accidentally glue the hinge permanently open. Very very disappointed.
