Joystick, easy to use

This joystick works great for my son. He uses it to play many different games on his cellphone and tablet. It doesn't have any adhesive on it but the way the plastic it made it adheres to the screen without any problems. We haven't noticed any sliding. It even came in a case that is made to the card so you have somewhere to store it when not in use. We did learn that the screen needs to be clean from fingerprints to make sure it adheres good.
