I would open the meter up and disable high voltage ranges if I feel that Stupid would be around! I usually work with mine (yellow case) under ~5V and I believe it is worth $4.99 to work under that voltage range. Simple equation 5v ~ $4.99. So I would buy it again for my tasks without any questions. I would also let my son use it on his arduino.
