Absolute junk. The first time I used it it read open neutral in the entire house. I started freaking out that there was a major wiring problem. Luckily I tested it in another house and got the same reading so I became suspicious that the tester was bad. I bought a different brand tester....and sure enough...the wiring was good...but the Sperry tester was defective right out of the package!
