My main initial concern is how you would go about carrying it around. It says to keep it away from phones, credit cards, etc. Does this come with a carrying case of some kind to protect your other items? Very interested to see the full capabilities of what the device can do!
To add onto what Lyle said, the Distancia device does come nicely packaged in a box that resembles what you would get if you purchased a nice watch. When not in use, we highly recommend storing it inside the box it came in (the black box) and storing it away from any electronics or metal that would be affected by a magnetic field. The magnet is strong - the accessory kit that it comes with comes in a separate box and even that can get magnetized to the top of the Distancia box if the device is inside. It's good for making sure that everything stays in one place, although it is a sign that it really is powerful.
When using it in performance, for example let's say it will be strapped to either your right arm or right leg. If the device is on the right side of your body, we recommend storing your phone, wallet, keys, etc on the left side of your body, so in your left pockets. If you are wearing a watch, make sure it is on your left wrist keeping it away from your right side. If you decide to take the device off of your arm or leg and you do not have the storage box on standby, you can place it in your pocket on the opposite side of any phones, wallets, keys, watches, etc. However, we recommend this ONLY if you absolutely cannot store it inside the box when not in use as this is intended for professional use (not a toy!).
