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.

I run a bunch of 3D printers and recently had blown several fuses - I needed to be sure that my power strip and socket was not the issue as the expensive cost of having under voltage or a loss of ground was not something that I wanted to risk - this one is incredibly easy to use - multiple error detection codes that can detect several different faults even button to ensure leak detection receptacles are working properly - hands down the easiest way to check your sockets at home for faults and correct voltage! 10/10 recommend this one for any DIY home owner!

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!

Good

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.

It doesnt get any easier then this, its basically idiot proof, the proverbial plug and play. Ordered this because when I run to circuit braker the misses knows right away that the outlet is working instead of her having to plug in leads and test for voltage.

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 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.
