Originally used to show off the Samsung Galaxy Fold. The bases light up blue and look nice when on. The cases lock with electronic keys and one of the keys turned blue when I used it with the unlock scanner and I was able to lock and unlock one of the cases. The other light did not turn blue and I was unable to unlock the other case. I’m not sure if this could be the keys are on a timer or if you can somehow only activate one at a time.
