The blue tooth keyboard case was easy to pair to the iPad. It comes with a charger. The case is nice and slim its not bulky as you might think for a keyboard case. I like that there are multiple angle options for propping up the iPad. The magnetic closure is good and strong. I just wish that it would auto sleep and wake upon open and close.
Output:
