The acrylic backboard is placed directly on the computer bracket, and then you can't write hard on the ipad.

In the library: just put it on small items such as glasses boxes/milk boxes, and don't worry about bending! Unless you poke a hole in the screen with your strength [doge]

Another important reason to buy it! Just don't have to buy an expensive and heavy three-fold shell! And don't worry about bending when writing! You can use a shell without a cover directly! Back? When you put the board and ipad together and put them in the computer compartment of your schoolbag, you are not afraid of being crushed, so you are relieved.
