I personally do not have an iPad, but seems like a great case with keyboard for the ones that do.
Opens like a laptop with magnets hold screen up, ultra thin and light
Sound waves two times powerful than without the case
Extended battery life: 1900 hour active battery life/ 4,300 standby battery life
Matches your viewing angle: 25, 30 or 35 degrees
Wakes up automatically, non on/off buttons
Auto wake works on only 3rd and 4th gen iPads.
