Great compact tester. I wanted something small that would allow me to quickly test that all the outlets in a new house were correctly wired as the previous owner did some basement finishing work on their own that had not been done under the proper permits. This tool gives me the piece of mind that every outlet is setup correctly and that I won't have any surprises in the future. Since it doesn't have it's own power there's not much it can tell you if the hot is missing, as the unit won't be able to turn on at all... but if that's the case you're going to be fixing the outlet anyways so to me this isn't a big deal. I also really like that it has the GFCI test button. Some people may think that this isn't useful since GFCI outlets always have a test button on the outlet itself, but the beauty of this tester is you can use it on outlets further down the circuit that are protected by the same GFCI. For instance, if you have a GFCI on your kitchen counter you can plug this into a different outlet on your kitchen counter and verify that when you press the button on the tester the GFCI on the other outlet trips. This is also useful as a quick way to determine which breaker turns of a particular circuit. Test it on a known good circuit, plug it in to your target outlet, make sure it lights up, then verify that it turns off with the breaker you expect. At this price everybody should throw this useful tool into their bag.

Sperry Instruments GFI6302 GFCI Outlet / Receptacle Tester To use this tool just plug it into a wall receptacle. LED's will light up on the end of the tool letting you know if the receptacle is properly wired. Key codes are written on both sides of the tool to let you know what the lights mean. I installed additional electric wall receptacles in my 1945 townhouse and found multiple ground wires in the walls, some of which were useless although they showed a 'ghost current' on my multimeter. This tool allowed me to quickly find the proper wires, making the job so much easier. Testing existing receptacles around the house showed that some of them had been improperly grounded for many years - likely dating back to the 70's when the TH was renovated. Excellent tool, and highly recommended.

After being an electrician for over 39 years & being an electrical inspector for over 15 years I have found that this tester is the best I have ever used, & I have used them all!

This is a review of the Sperry Instruments GFI6302 GFCI Outlet/Receptacle Tester. After reading the reviews, it appears that Amazon has grouped together the reviews for a number of similar products. So you need to be sure which product you're reading a review for, if that's even possible. Seriously, Amazon, this makes no sense. But, back to the review. This product seems to work perfectly, so far. It is very simple to use. I was actually quite amazed at the quality with which it was built. For less than $8, I expected a light weight, cheaply made item. This item appears very solid and put together well.. The metal prongs that you insert into an outlet are thick, solid metal. Not flimsy at all. It weighs more than I expected, which I'm hoping is an indication that it's made with quality components. I really can't find anything to complain about. It appears, so far, to be much better quality than I expected for the price.

Probably anybody buying one of these knows what they do: they detect AC voltage from 12 to 1000 volts (12-1000VAC) not by using a meter, or by physically contacting the electrified part, but by getting this device near. They are in common use by professionals and others that regularly work with, or could be exposed to dangerous AC voltages & current. Telephone repair workers, for example, carry them because they don't know when some enclosure they're unfamiliar with might be electrified. For others: have you ever touched an appliance that was wired to a faulty AC receptacle or with an incorrectly wired ground & gotten shocked? Have you ever looked at some exposed wires & wondered if they were "hot?" I used this the day I got it. I had some plug-in lights that were out. I knew the AC receptacle was putting out power because I tested that, so the fault must have been somewhere in the string. I used this and quickly found out exactly where the break was, and fixed that. Day one I probably saved 45 minutes, and I wasn't even using it for what I intended to. AC power can be a tricky thing, even in residential settings. The notion of "hot," "neutral," and ground are dissimilar to the DC world, & can easily get messed up if work has ever been done on any AC wiring. Having a device like this helps one to avoid dangerous voltages. You can even trice wires in walls! I set the "sensitivity" by getting it near an AC receptacle I knew was good, & then turning the sensitive knob until it reliably registered when near the receptacle. I wish their was a more scientific way of setting the sensitivity, but the manual didn't have any instructions regarding setting sensitivity. If you've ever been zapped by an improperly w

I was looking for a simple, no nonsense 110VAC wall outlet voltage sensor at an economical price. This is it. Place the tip of this device about 3 inches from your wall outlet, keep the ON button depressed and adjust the sensitivity dial until there is no beeping sound. Finger off the ON button, move the device so it just touches the wall outlet and hold down the ON button. Increase the sensitivity dial until it starts beeping and the light goes on.. That's it. No need to do anything else after that for all future checks on your wall outlets. In my case, with the sensitivity set this way, I can move the tip of this device along my (5/8" sheetrock) interior wall AND IT DETECTS THE WIRES WITH VOLTAGE BEHIND THE WALL! A real bonus for a unit at this price point. Nice and compact, appears to be well made. Ordered 2 more to be sent to my adult children for their home toolbox. A good household safety tool as well as a good troubleshooting tool. You won't be disappointed.

I have owned a few of outlet testers and this is the best. The lower priced testers have lights that can "bleed;" that is, visually interfere with each other. Also, those with a smaller number of indicators don't always clearly differentiate between different problems. If you've never used these testers, I think they are probably one of the most important household items to have on hand. An outlet with an open ground or wrong polarity can be very dangerous. We purchased a home that had been remodeled and I discovered that some three-prong outlets were actually never grounded. The circa 1950 early Romex wiring had no ground wire and some electrician took a shortcut by installing a modern outlet.

A rugged well made tool that works very well. Same hi vis yellow plastic and black rubber grips as Dewalt Tools. I really like the adjustability of it. At full sensitivity, I get it within a few feet of a circuit or fluorescent light and it starts buzzing. All the way down and it does not detect anything, so the range of adjustment is fantastic. I can dial it in so precisely that I can hold it on one side of an insulated wire and it will not go off, but when I move it to the other side of the wire (where the hot conductor is) it goes off. That's accuracy to a few millimeters. Best way to use it is to calibrate it ahead of time. Stick it in the hot side of an outlet, on a wire or conduit, hover it over a wall switch or outlet that you know is hot and adjust the knob until it buzzes, now it's ready to test the unknown circuit. I live in a 60+ year old house with plaster and chicken wire lathe wall construction. At a little more than 1/2 sensitivity it detects the wires inside the wall, inside of metal conduit. By moving it back and forth and seeing where the buzzing starts and stops, I can trace exactly where that wire is in the wall between the studs. Makes it easy to trace or detect wiring in the walls before I cut or drill through. If you will only use one of these to stick into outlets or against wires to see if they are hot then the adjustability feature may be overkill, but to get a lot of varied use, I'l glad I chose this one.

My wife and I were recently shopping for a new house (our first home, no less), and I brought this product along to make sure that the "updated" electrical systems in the 90-100 year houses were truly updated and not just grounded outlets slapped onto non-grounded wiring. This device quickly and accurately let me know which houses had major problems which potentially saved us tons of money in the long run. Would recommend to anybody who needs to test outlets that they have installed, or to test outlets in potential future homes. P.S., I understand that testing the outlets in somebody else's home is probably borderline unethical, but I think that selling a home on the pretense that the electrical is updated when it actually isn't is far worse!

I knew something was up when my GB Electrical 'two-light' outlet tester that I've been using for years told me a circuit was wired correctly but when I used a GFCI tester on a GFCI outlet it did not trip. The GB unit has been pretty reliable but I knew it was not giving me correct information in this case which was my impetus for buying this newer, digital/single LED tester. You can see in the pictures attached to this review that this Sperry LED unit is correctly showing a bad ground and the other tester showing the two rightmost lights turned on--that means it's saying the outlet is wired correctly (which it is not.) Also, in case anybody is wondering this Sperry unit has the labels for the LEDs on both sides so you can still read it even if the outlet is upside-down.
