I purchased this for $20 on Amazon and never used it. It’s works just fine and helps a lot whenever you need to write a essay on the road or anything else. It has a prop on the back to stand it up and will hold most phones. It connects via Bluetooth and has a pretty good battery life. It uses a android charger(included). It also uses magnets to hold it down so it won’t be sliding around any. Message me if you are interested or have any questions!
