Power Gear 3-Wire Receptacle Tester, 50542

I love this! It is so much easier than a multimeter if you don't need all the bells and whistles. You just plug it in and it tells you what's going on with your outlet! It's very small as you can see, it fits in the palm of my hand and I am a very petite woman. I like that it is so small because I can take it with me because I use it for my earthing mat to make sure that the outlet is properly grounded. Since I used the grounding mat in other places besides my home. I can just stick this in the Box of the groundy map and take it with me to ensure that wherever I go. I can check the outlet!Thank you for this tool! It is extremely easy, inexpensive and works great!!!!!!!!!!!!!

Works perfectly, and great build quality, but doesn't have a button to test GFCI. This is what I wanted, but may not be what you want. I had an issue with an awkwardly placed GFCI plug - and I kept accidentally pressing the GFCI button on my other tester, which tripped the GFCI breaker. Annoying! This tester was the perfect solution.

Excelente producto a muy buen precio. Permite identificar fácilmente los contactos conectados erróneamente. Muy útil, de construcción sólida y con instrucciones incluidas en la calcomanía del producto, solo hay que destacar que estas se encuentran en inglés

For the price, you get a full checkup of your A/C outlets. You will know if you have true ground and if the polarity is correct. Very useful.

Every home should have one to test the plug. I bring it with me when I go house hunting to make sure the wiring is done right. Cheap way to test plug.
