    Industry standard for a good reason
    no wonder it is the industry standard. Works wonderfully and provides everything one needs to test GCFI outlets. Basic stuff for your tool chest.

    Excellent tool. Gives information about wiring of receptacle. Can test GFCI. Also tells incoming voltage. Display is very nice and lighted.

    An essential tool for home safety! I caught an arcing outlet using this device!
    This is a basic, essential tool for confirming wiring safety in your home. I noticed that the top half of an outlet was behaving abnormally, and this tool confirmed my suspicions in less than a minute. When I replaced the outlet, I broke it apart and found arcing scorch carbon on the contacts, a definite fire hazard.Do yourself a safety favor and buy one of these. Their very inexpensive for their worth and they come from a quality manufacturer that has been well-known for decades.

    Reliable, safe, and easy-to-use electrical tester
    This outlet tester gives me a lot of peace of mind when working around the house. It’s simple to use—just plug it in, and the bright LCD display gives clear, easy-to-read results. The color-coded indicators and built-in GFCI test function make it incredibly functional for quickly checking outlets and ensuring wiring is safe.It’s also reassuring to know I’m catching potential issues before they become bigger problems. The build quality feels solid and durable, so I don’t worry about it failing when I need it most. It works well every time I’ve tested it, even compared to a more expensive professional tester.This is a perfect tool for homeowners or DIYers looking for something safe, accurate, and functional to check their electrical systems.

    Testing for voltage in outlet.
    Works good, but it is a little bulky.

    Absolute must have if you are working with GFCI outlets!
    I previously owned a basic GFCI tester (no display) and had great results. However, I found myself needing a bit of an upgrade so I could see the voltage readout for my outlets. This checked the box and is an absolute game changer for me. It had a better design, around the same size as the basic version, nice and bright display, but most important of all it is accurate. I can test GFCI outlets and get the voltage readout for any outlet in my home. It has helped me identify issues with lower voltage in some outlets and bad GFCI outlets. I recommend reading the instruction manual before using a device like this just to get accustomed to what it is telling you on the digital readout display. Overall, it comes from a quality brand, it is easy to use, so this is a must-have tool if you are working with electrical.

    nice upgrade from the cheap trash testers
    I’ve owned several “outlet testers” over the years but they’ve mostly been trash. Now that I have an attic to finish I needed to get something actually useful. After looking around I settled on this one, which is a kind of a middle of the road tester. In addition to the usual “you wired it up wrong!” idiot lights, it’s got things like line voltage display. I can also plug it into an outlet that’s in a hard to reach place, then pull it out and look at it to see if it’s good. It’s also slightly larger than the cheap junk, just the right size to fit comfortably in the hand and plug/unplug.I’m happy to have this in my electrical tool box, everyone that works on outlets should have one

    Amazing tool. Perfect for home-owners that are weary on the state of their outlets. Did a couple of outlet replacements and this unit came in handy to test and help identify faults. Even on GFCI outlets!
