I took my Sony Xperia z3 to be repaired front and back costing $280 on Tuesday 19th January. I distinctly remember them handing the phone to me with the back glass still a little loose which the repairman glued saying "you will not get a problem with this". Within 3 days the glass at the back of the phone was already peeling off causing a crack.

I took the phone back to Foneguru to say this is not on, you should not be spending hundreds of dollars to get a defected item within 3 days. I was told either they will glue it back or you will need to pay another $40 to fix (reduced from $65) which is poor business.

EDIT: Foneguru gave me a completely new back screen. Good move on their part but not the best of experiences.

Approximate cost: $280
