2 items from 5 were defective. Keep restarting by themselves after stopping. Does not matter the potentiometer adjustments, just keep restarting. No infrared sources are in the room (I stayed in the other room). Strange behavior.

Looks fine, not tested. Poor delivery estimate 14-23 days, was 33 days.
