I love this GVDA little voltage tester, its small and compact, and gives a voltage reading without the need for two test leads.
It can sometimes be tedious taking voltage reading with two test leads and holding the device being tested. This tester alleviates that with only requiring touching the hot lead. What I like is the metal tip of the tester which takes a physical reading and displays voltage, as opposed to other testers which just beep and/or light up if voltage is present. You can still use the tester without contact, but I prefer to make contact and take a reading. The tester also has a light on front to illuminate what is being tested.
