If your family is like mine, dead used batteries don't count and then we don't know which are good and which are dead. Well, you can test it yourself for around 10 euros. This is also helpful for making sure the correct switch is off when changing lights (ask how I know you need to check the wires). Ma charge that the battery should be. The backlight and rubberized case (with built-in kickstand) are durable and portable. Hubster has a $450 Fluke multimeter that he uses, but this one will be mine. I love the simplicity and precision. Great price for a product that pays for itself in a few months.
