thanks TS, received in nice! like it very much!

my comment,

nexus 4 with the Black/Grey Poetic Borderline Bumper Case &

SPIGEN SGP Nexus 4 Screen Protector Clear Steinheil [Ultra Crystal Dual] Clear Front and Back

both combined very well! bumper case didnt overlap the SP or pushing the edge of the SP! and after bumper case is on, N4 still slim.
SP is great, no cover front camera and the sensor, as for me this is the first time done by myself, manage to apply the SP front and back nicely and success

Ventilation is better than Ringke Fusion as N4 easy heatup when in high core usage, and best is max expose the sexist back of N4.

cheers!
