I had dropped the iPad and cracked the glass, so I hoped this was a viable path to fixing my iPad. Instructions are good - key is to heat the iOpener and ensure the adhesive is soft - with an 1000 W microwave, it needed 2 x 30 sec to really warm up. I was able to follow the instruction but the digitizer had dead spots so the it was not possible to use the keyboard. I thought it might be dirt between the glass and the LED, or possibly a loose connection so purchased fresh adhesive tape, removed the glass again, reset the connection and carefully cleaned both the LED and the screens before reassembly. Dead spots remained, but fewer and in different locations (!). After a couple of days, the LED has died. Lesson is - don't drop the iPad.
