Positive: Good screen, perfect and responsive touch, nickel color I find my pre nexus
Negative: very very bad quality tools (do not count on it to install your screen: the Phillips dropped me from the 2nd screw), no double sided tape or glue, no filter for LED notifications (it lights up very strong) but that poses no big problem.
I would do the purchase without bp. Installed today remains to be seen lengthwise.
