STM Dux Shell Sleek Case for Apple iPad Pro 12.9, 2017 and Generation 2015 - Black (stm-222-163L-01)

will this work "seamlessly" with the apple smart keyboard, i.e. turn off screen when cover closed? one reviewer says no... anyone else?

Anyone have difficulties removing the pencil?

will a smart cover work with this case

What are the dimensions of the case with an ipad in it and a smart keyboard on it? H x W x D in inches please.
