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

Used this recently while I was setting up some new outlets and have used it helping some friends with electrical work. It is a great way to double-check if you are doing everything correctly. Super easy to use and understand so even someone doing a DIY outlet repair or just checking through your house outlets for any faults. I wish the screen was at a bit of an angle because especially on outlets lower to the ground the viewing angles of the lcd are not great, just angeling the screen up a bit might have helped. Overall a pretty good device that I am happy with.

The meter is about 2 vac off and the hz reading always shows a steady 60hz even on a generator that was running at 64hz.

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.

Worth buying.

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.

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 have a similar device that just has colored lights and costs less, but this is easier to read. It also will test for GFI working correctly. I talso shows you the current and frequency. If it trips when you plug it in for GFI, that is the purpose, to test it. If it does NOT trip when you are testing it then you are not protected.

worth the cost if you are uncertain about quality of install

This outlet tester is super simple, has a great digital display that is easy to read and its pretty compact for what it can do! Just plug it in and it will tell you if its correct or not, and the amount of voltage that is coming your way. Doesnt get any easier than that!

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.
