Installation instructions was not available but you can find on the net so enough. I have used the image-for-image-guidance of idoc.eu. Since no tools are included, you should have at home (in the above link shows what you need). Installation was completed within half an hour.
Display works great. Making a difference to the original wirds probably give but I could at least find no difference in quality. The display fits perfectly and leaves no gap left (when correctly installed). The image is sharp crack, has the right brightness and also displays operation moderately (touch) no deficiencies. I am very happy with the product.
