Water proof and shock resistance. I've dropped my phone so so so many times and not once did my phone crack. I've dropped my phone is water and my phone works perfectly fine. Although when it gets old, the color of the case can change.
The design is cute. I love how it fits in my case. Taking it off is a little struggle but it's worth it because I have a terrible habit of dropping my all the time. I bought mine at best buy and totally recommend
