We were looking for a versatile support for placing the tablet on the kitchen wall to follow recipes, and also to install it in the car to distract my son on long journeys. This is perfectly possible to position in portrait or landscape, to connect the charger ... Installation is easy, only one set screw (supplied with screws and dowels for wood or concrete, I put a peg to the moly plasterboard). Contrary to several reviews, I find that the spring support is strong enough, but it remains to be seen over time. As for us, it usually remains hanging in the kitchen, so the spring is not really sought. It now expects the support headrest for the car, and it will be completed.
