We got our bendy glasses for Noah, and well, I think they lasted all of two weeks. He discovered twisting them had no effect (other than making it hard for them to stay on his face). So he found a new way to destroy them. He decided to throw them in the rocks in the backyard. So yeah, they had about 5-10 good size scratches on each lens. Good thing we paid for the one year warranty. So once again...we wait for the new ones.
