RIQINXIN Socket Tester Electrical Receptacle Tester AC Outlet Plug 3 Prong Circuit Tester Pack of 1

Ive had similar devices like this in the past and this works just like them. There are 3 lights and based on which lights come on when you plug it in you can tell if your outlet is wired correctly. Its a great tool for a quick check. This one works well and I seems to work well.

It works as intended; very reliable device and useful. I tested it in different wall outlets or even in my solar panel system outlets, and this device lets me know if there ground is wrong or any other error. This is something everybody needs to have. No grounded outlet is a real danger. Excellent product.

If you do any kind of electrical work, you must have one of these. The professional use them so if youre a home DIYer, you should too. Its invaluable to let you know if youve done the wiring work correctly or if youre trying to track down a problem. Like me, I just bought a house and used this to find that whoever had been doing work on the electrical here, didnt know what they were doing. I was able to track down some issues and correct them before a fire started or someone was electrocuted. Always keep one of these in your tool box.

This very handy tool does an excellent job at indicating whats what with electrical plugs. I am so glad that I found it, as it saved my bacon when I used it to make sure a socket was cold that I thought I had flipped the breaker on so I could change it, only to find, after plugging this grand device in, that the plug was still hot. Whew!
