2 - 4 horas
The ipad was dropped and needed a new digitizer.
The repair took several hours and was not something I'd recommend for the faint of heart but it saved me a bunch of money.
Take your time with this repair especially with the WiFi antenna as it rips easily when trying to remove the front glass, hence why I had to buy this part. This job is especially messy when the front glass is shattered. Also, the internal screws are extremely small so make sure you are working in an area that will make the screws easy to find when they are dropped.
