Sperry Instruments GFI6302 GFCI Outlet / Receptacle Tester, Standard 120V AC Outlets, 7 Visual Indication / Wiring Legend, Home & Professional Use, Yellow & Black

It is accurate and very helpful in determining polarity and testing ground-fault receptacles.

A very handy tool for the bag

It does everything I need it to do. The only reason it didnt get a full 5 stars is that one of the lights is off-center, and sometimes hard to see.

The product serve the purpose. Easy to use and the display is self explanatory.

I love it at a great price to boot.

Dont need to worry about losing the manual because instructions are printed right on the side.

Works Good. Notes dont say that the Test Button is for GFCI only, but it is. When Test is pressed, there is about a 20 kilo ohms resistances across the hot and ground prongs. At 120 volts that would draw about 0.006 amps or 6 mA. Which would be 0.72 Watts or 720 mW of power used. That wont trip a standard circuit breaker, but if Test Button was held for long periods of time on a standard breaker circuit, it could ruin the 20 kilo ohm resistor in the outlet tester.

This little tool has saved me from getting zapped several times. Also helpful for checking outlets after rewiring.

ok

Worked as directed. Helped me figure out my problem. Good little tool.
