Quality control took a vacation, but at least it works!
The case is solid, and, generally speaking, you can sit on it without breaking it.<br /><br />However, the hinges feel fairly flimsy, and after using this product for several months, I'm starting to think it won't protect my sunglasses as much as I thought they would.  The top and bottom halves don't match very well, so occasionally it is possible to close the case with the halves slightly offset, and the moment you put any weight or pressure on it, the halves collapse in on themselves, potentially crushing your glasses.<br /><br />I recommend this case if 1) you are on a budget, 2) you don't do anything besides put it in a purse or glove box, and/or 3) you don't use it very often.<br /><br />I give it three stars because you get what you pay for and it certainly works... just not as well as I had hoped.
Rating: 3 stars
