Unfortunately, the information on other cases is unclear whether the shell are also attached to the Air 2, which would be unlikely due to changing buttons on the device. So I bit the bullet and here slammed (18 instead of 3-10 elsewhere).
I knew CoolBananas however already by earlier and was then already of good quality and convinces fit. And so it is here:
All buttons can be pressed well, all microphones are free, the speaker and camera of course and both the original and fit the Amazon charger.
There is also space for the Smart Cover (Christmas? Screen protector is not an option) and the shell fits just really good, not too tight, not too loose.
