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

this makes checking your outlet a breeze. The LCD screen is easy to read. This is a great tool to keep in the toolbar to check if there are any issues with outlets and GFCI. great product.

The grounding pin came out the first time I used it. I like the concept of the ease of use, but needs to be built better.

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.

Always had a problem with electronics sparking when plugged in, turns out 3 outlets were wired wrong. This thing told me what was wrong and I re-wired them myself. No more problems.

I have plenty of experience with electrical systems and own many different types of testers like this. What sets this one apart is that is provides plain-language messages about problems. This is ideal for the average homeowner who may have no knowledge of wiring. It tells you exactly what the problem is, in words, making it easy to fix the problem. It works very well, and I would recommend it.

I like that this unit will diagnose the fault in the circuit. I also like that it will cause a fault in the circuit to test the protection of the circuit. If I never encounter a problem that is diagnosed, this is a good thing! Reading the screen cannot be much easier too! I LOVE THIS UNIT! This unit covers much of what I would do manually. I have done a lot of wiring in my house as well as others and formerly in my business too. I have always elected to use my multi-meter so that I could ensure good connections (checking voltage after knowing the supply into the premises). I would check between all three connections as well as the chassis (box), especially if using conduit or metallic shielding. Using this unit makes it easier to get past the shields in the better duplex receptacles (wall plugs) and it gives me all the readings I would use. I do recommend this unit especially since it is CE certified as well!

worth the cost if you are uncertain about quality of install

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.

I like this outlet tester because its very easy to read, and does give you some more information beyond the 3 lights the older style testers have. Great to keep on hand in the tool kit to test outlets.

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.
