Ghost Armour screen protector is fantastic. The fit goes to about 1mm from the edges when fitted correctly. The 'feel' is better than Zagg on my better-halves SIIx. $15. Recommended.
They also had coloured carbon fibre body wraps and claimed it would protect equally to my Otter Commuter; I disagreed. The back is 1 piece but they had 6 pieces for the sides. The is no way it would do anything but save the device from scratches. $35. Not Recommended.
