The Case Mate is pretty nice but for me I wish the camera/flash cutouts were to exact sizing like Tudia did with their TPU case.
The Tudia case fits really well, they have two version, one for BN and one the regular turbo. I have 3 cases, clear, blue, and black for my BN Turbo. I like the black one the most, look real nice. The clear/colored one fits well too, there's a slight problem with the flash when taking picture, since the colored case are clear, the flash will reflect the color on to the image, so if you case is blue there will be a blue haze in your picture.
