One morning a few weeks ago, I was getting out of bed, grabbed my phone, but in my stupor, sent it flying across the room. I was lucky it landed on the battery door, and didn't scratch. Regardless, I've been awfully lucky in the five months I've had it. I decided to get a BB Transform Shell, because I wanted the slimmest form factor, and I wanted a BB OEM product.
If anyone is thinking about getting one for Z10, I can recommend it. It still allows me to slide my phone into my pocket, and the kickstand feature has come in handy several times already.
