Function as the cursor and the board as the screen, when you move the pen to the corner of the board, the cursor on your screen moves to the corner of said screen, etc. (Compatible with Windows XP/Vista/Win7/8/10 and Mac OS 10.8.0 or above. ).
Took a while to set up and link to Mac computer but once it was done it was absolutely a breeze to use.
It's great for creating finer details in graphics and in my drawing - used it to create those difficult to access parts in drawings that a mouse just cant do as well as a human hand.
It's great! Ideal for beginners and new artists as it's reasonably priced.
