Review: Here's a tester everyone should own. Works and takes a beating around the garage. Displays actual voltage and Glows Green if polarity is correct or red if reversed so always easy to determine Ground and Positive power wire. Much better than testers that just beep or light up. The voltage reading is very helpful and i use it all the time. The probe end is sharp enough to pierce wires to test and the alligator clip is a good size and clips on securely. Best tester by far I have ever used.
