I've purchase 2 pair of these sunglasses because I really like the look and they are inexpensive. However, that second part may be the reason I have had to buy them more than once. In both occasions, I had to replace them because the frames cracked around the lenses, making them unusable and un-repairable. Not dropped or anything. Maybe it's their exposure to the constant sun and heat here in Texas. In any case, moving on to more expensive brands to see if they fare better.
