One problem with that device is the receiver decides he is not going to pay for the shipment so he slaps the face of the device with his hand the beads fly everywhere in the arrow and static holds them there. I have seen similar things happen to driver who was carrying some very shock sensitive equipment with those shock sensors like they use in crash tests placed all over the carton Some how from the time the carton was unloaded to the time it was hauled inside of the lab where it was going every sensor on the outside of the carton had been set off. But what the dock worker didn't know when he slapped each sensor changing their color was there happened to be a second set of even more sensitive sensors located inside the carton on the piece of lab equipment itself which had not been set off, The driver got paid the worker got fired
