Hi. I've ordered many screen protectors for my sensation xe and these are the best so far. Many others were far too small mainly to accomodate for the sensations curved screen edges. So once its on u can tell straight away there is a screen protector on it and looks a bit daft.
These ones are the biggest I've used. They fit pretty much, the whole screen. Approx 1 millemeter is left around the edge.
I will say because of the bevelled screen edge, there is a very slight line around the edge of the protector because of the lift but its less than a millimeter and hard to notice.
I've had mine on for a month and it looks no different.
Basically, if you are very careful and patient when applying the protector on, it should stay on no probs.
