I have neck and back pain. This product allows me to place my iPad/phone at eye level and use the device hands-free without having to strain to hold, type and view while sitting in my chair. This is sent from God. I added pictures. Installation is easy, although you'll need some patience to put your hand on the pole (be careful not to break the plastic liner inside, it's tight). Also, I rotated the bar to adjust the hand position. (The instructions show the hole aligned with v of the base.) You can position yourself to work to the left or right of the chair.
