After futile attempts to repair the Home button of my iPhone 4 with the aid of contact liquid, I made it easily with this spare part and the tool provided. It was the first time that I have an iPhone open, and must extend to the Home Button before out as good as any other part. The tool provided fully meets its purpose and is complete. Only a pair of tweezers I've taken to help to place the washers of the display screws during assembly. That the screwdriver are magbetisch, wherein the tiny screws of great advantage. And the component itself works as stated properly. One can unfortunately test until everything has been reassembled, and so my joy was all the greater. Instructional videos and illustrated descriptions found on the Internet, so that the repair was not a problem.
