The slot contains both the tablet and the phone with my cases and glass covers, but when I put my S8 Active in its Supcase Beetle Unicorn case, it is too thick. It didn’t take me time to get used to the keyboard, since the design of the keys corresponds exactly to that of my Tesla keyboard, except for the arrow and the start keys. I use a mechanical keyboard on my home computer, and when I try to use the flat or soft keys, I spend all the time on the backspace key. The input is clear and clear, and I really appreciate the fact that the keys are not dead or soft. Super easy setup with my Asus Zenpad 3S 10 and my Samsung Galaxy S8 Active.
