Just applied the Vikuiti DQC-160 screen protector. Went on perfect the first time, no bubbles. It is quite a rigid screen protector so nice and easy to line up with the top of the screen and then push down with a credit card so its flat and straight. Almost un-noticable except for where the holes are for the proximity sensor and phone speaker. 10 x easier to get on than the Durasec which went in the bin after trying several times and ruining it. No noticeable affect on screen sensitivity. One happy customer.
