It is the second that I buy and it is still not working. I bought a first in September that worked. Then with updating my iPad 4 iOS 7, he started to display "non-compatible hardware." Novago then explains that this change is beyond their control and that as of 25/10 we must buy another for compatibility with iOS 7. (meanwhile they try to sell their stock of old models to 3) WELL NO !!! DOES NOT BUY ABOVE, THIS MATERIAL IS DEFINITELY MORE COMPATIBLE WITH YOUR IPAD 4 sub ios7
