I place this at the front of the room and every time the students need to use the headphones, flash drives, cameras, etc...they simply sign them out and use during class and then check that they returned them. They also report anything that might be broken or not working. This saves me time issuing out the needed supplies. Students really take ownership of the class materials too, and take good care of them. I have 20 headphones, over 40 flash drives, 10 cameras, 5 microphones, and much more that they take care of.
