Best keyboard for my iPad AIR

Had for my old iPad3 already the Logitech keyboard which had a similar design - only this was not lit and had a few less features.
The Kensington keyboard is similar, is probably the successor.
The lighting is really great, can be dimmed and adjusted even in color.
Keystroke is ok for me, I write quite fast with 10 fingers, which works great. The anchoring of the iPad is also sufficiently stable - on the feet should be the combination but not balance.
I would buy the keyboard again, value for money makes me happy.
