After the daughter dropped her iphone 4s on the tile floor and the display was quite over, I had a look at Amazon for suitable substitute and came across this product. According to some reviews it should be good, provided, albeit with a slight "gray cast", be because it was cheap but I chose this small drawback (if it should be because so) to accept and ordered the display. The delivery was accustomed quickly.
Installation I had first studied at YouTube in a video and then performed accordingly. Then after tricky detailed work of great moment; what can I say: actually display appears gray and washed out, I thought it was at first for normal, since the read reviews sometimes referred to it. The daughter liked this but not so she knocked immediately around on her cell phone and suddenly the image appeared as usual (albeit briefly) in bright colors, so I took again it all apart and triggered specifically the ports of the display at the Hauptpaltine again and fastened them again, just as the present there have cover very thoroughly screwed and lo and behold, now everything is in order. No gray haze far and wide!
Great product, strong buy recommendation, earned five stars :-)
Addendum:
After about two weeks, the display has given up the ghost, I turned then to the seller, describing the event, I received immediate friendly response and two days later for free a new display, this carries far its services properly, I certainly hope that it is so remains.
In addition to the good product now just adds exemplary service, so I stay with 5 stars.
