Aicevoos D2S Receptacle GFCI Socket Outlet Tester with LCD Display, for Standard 3-Wire 120V Electrical Outlets Tester

worth the cost if you are uncertain about quality of install

This unit works so well and simply that even those of us who lack any understanding of electrical circuits can troubleshoot an outlet. Plug it in and watch it work. It is sophisticated enough to diagnose that my smart outlet expander is lacking a ground, despite it having a ground lug. I used it immediately to determine that my wife had turned off a light switch to a series of outdoor outlets, despite her protestations to the contrary. It was very nice to have an expert on my side.

I plugged it in, showed no ground, Im thinking WTF I know this is a good plug. I pull it out and the ground prong is still in the receptacle. Literally broke on its first use.

This is a great tester to throw into your electrical tool box. It is small and easy to use, and doesnt even require any batteries. Simply plug this into a standard 120V outlet and it will, within about 3 seconds, tell you in plain english, if the wiring is correct, and the voltage and frequency of the AC. If there is a problem the tester will tell you in words what the issue is, without having to interpret a set of lights. Additionally, you can press the leakage test button to trip (test) a ground fault detector if there is one in the circuit. This will handle up to 250V so if your socket somehow has 240V instead of 120V on it, you wont blow up the tester. PROS: * Small and lightweight * Good build quality * Extremely easy to use CONS: * Consumer quality, not a professional quality product.

This Receptacle Tester is literally IDIOT PROOF... All you have to do is just plug it in and within seconds you get an accurate digital readout. Its great for DIYers as well as the Professionals. I highly recommend this product for everyone.

This thing works great and is so easy to read. It’s just slightly difficult to store. I wish the plug folded into the main unit, rather than remaining rigid - it would just make it that much easier to store. Other than that one thing, this thing is so much easier than the old “decode the 3 lights to see what state your outlet is in” reader it replaced.

Worth buying.

This tester has a nice solid feel to it. A little bit on the bulky side but still fits on most outlets without too much getting in the way. Unlike others Ive seen, this one is does not require batteries and powers up using the outlet its testing. With that said, there are no fancy functions. It simply displays 1 of 6 preset messages describing how your outlet is wired or what wire is missing, along with measured voltage and frequency. The RCD button is for testing GFI outlets tripping function. Other than that it does nothing.

My Dads older home still has some 2-prong (non-grounded) receptacles. I wanted to test them because grandfathered into old building codes or not, I dont think theyre safe. So when I saw the Aicevoos D2S Receptacle Tester I jumped on it. Of course, I failed to read the entire product title or I wouldve seen that its for 3-wire 120V outlets. DUH! So that was my bad... The good news is I can still test all the 3-wire outlets in his home and every outlet in my home too. I like the simplicity of it. Plug it in, let it do its thing, and then get a result on an LCD screen. Much easier than having to look through a reference chart to see what it means when certain LEDs are lit up in a certain order. Personally, I think everyone should go through their home or apartment and test all the outlets for safety and peace of mind. You probably werent there looking over the electricians shoulder during construction. But at least you can get your kids (if old enough) to go around and plug this device into every outlet you have. And if any of them display anything other than CORRECT, youll certainly find out about it in record time! (ha-ha)

Surprised at the nice appearance of this for the low price. Very pleased with purchase!
