These originally retailed for $129. It's designed for the iPad Air. However, I just attached an iPad Air 2 and it fits really well. It stands in the keyboard slot perfectly as well. I'm yet to fire up the keyboard with either iPad, but it's just a Bluetooth keyboard, so it should work with any bluetooth device (including the Air 2).
I've noticed a few good deals pop up from this seller. It seems they source excess/older stock from companies and sell it off for low prices.
Tested the keyboard with the iPad Air 2 and it works. So this does the same job as the Air 2 version, for a fraction of the price.
