I tried 3 different tablet stand for 13.3 inch Max Carta.
But this is the best one. Because it can hold it stable and prevent from falling even you poke the screen with stylus. It doesn't touch the power button in the bottom, which overcomes the accidental turn-off issue caused by the worst design ever.
