It adds resistance to the pen, being that rhe glass is very "slippery". I do not use the tablet for artistic drawings, but I do use it to draw diagrams in troubleshooting in the world of IT.

Regardless, it makes enough diference that I would recommend this, and i think the price is fair for what you get. One last detail, the look of the screen is as if you had a matte screen protector.
