Used this to inspect the outlets on a new construction and was very pleased with the response and ease of use. A handy instrument to have whether you're an electrician or not.

Recently purchased an electric Scooter (think electric MoPed). My second trip out I ran short on battery power and had to make a stop at a friend's home to charge up for a couple hours. Discovered when I got home that the outlet I used was a GFI plug that had been tripped and thus did not charge the batteries the previous night. This would have allowed me to check that condition. I intend to carry it with me to check outlets I can charge from when away from home.

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.
