I picked one of these up recently. My biggest question is what do you do to keep your phone or other device from overheating? Most phones want to overheat when outside in the summer heat, and that's just sitting there.
Just put in the shade from your body or in your pocket, But once you have paired your phone to the ConX once the data is loaded in the phone it will then send it to the ConX and you don't need your phone again.
