Hi everyone, I'm looking for a solution for locking down the iPads on panels for our annual design exhibition. Last year, we had tethers that were attached to the back of the iPads via an adhesive pad, which worked just okay but I am hoping this year to find something better. We are trying to avoid hassle un-looping the tether from the metal bars on the panel each time we want to charge the iPads. Does anyone have any other suggestions? Thanks!
