ii i just did this and it took a while but i figured it out it is true this thing doesnt get hot enough BUT heat it 2 times and then the 3rd time when u place it on the ipad put the ipad box on top and then maybe a second ipad on top of the box so it kinda smashes i down but not too much for it to break and then wait for it to turn warm THEN use the succion THEN the gap appears. the glue is super strong on the ipads so yea it will take some time lol
