Carbon fiber is supposed to be light and strong. This was just cheap and brittle, and snapped the first time I used it. It has no face cover either. I should have known when the directions said it was delicate. Poor product for $60
As we mentioned in our e-mail conversation, I'm sorry to hear that your case broke. This particular case is not meant to be rugged and provide a ton of protection outside of scratch protection. It's meant to be minimal and transform the look of your watch with a really cool material. While carbon fiber is known to be super strong, it takes using a lot of layers to get it that way (the more layers, the more rigid). In this case, we use the minimal number of layers possible to keep it as light and slim as it can be. While carbon fiber can be strong, it depends on the application. In this particular application, carbon fiber is not being used for its strength characteristics, but rather it's appearance and weight. We certainly understand that's not for everybody, and I'm sorry that didn't come across before you made your purchase.
