Checked it out, someone said that it covers up the proximity sensor?
"I am a pretty avid Realook customer, you can't beat the quality in my opinion, and I have even evangelised them to my peers.
I have purchased a Realook screen protector for all my screened gadgets. They are very durable, not grippy to the touch like the wet application competetors such as skinomi which leave a wavy ripply finish, and most imnportantly, completely invisible.
Their fit is typically highly precise as well.
However, for the Moto X there is a glaring and disappointing discrepency. Depsite the usual attention to detail from Realook, they have neglected the cut-outs for both the proximity sensor and front-facing camera of the Moto X. This may not affect the camera, but it is a deal breaker for a proximity sensor, rendering it almost inoperable. I was forced to perform my own cut-out before application and the result is less than satisfactory."
