Works just fine! But, you can hardly see the lights under any lighting condition!! The way the lights are designed you have to be looking above the tester and is still very hard to read, The red light is not bright enough for the cover they have put on it. Good luck using it outside on a nice sunny day!

Greenlee is a quality product! It’s dependable & idiot proof. I had to replace my initial GREENLEE GT 10GFI plug tester after over 16 years. My initial purchase came in a GREENLEE zippered kit, including a tic tracer & a meter. All except the plug tester are still going strong 💪! I’d recommend this product. Hopefully it will last as long as my first one did. Thanks Greenlee for quality products!

Reviewed in the United States on November 13, 2011
Style: GT-10GFIVerified Purchase
What can you say about a circuit tester? It works perfectly and is a Greenlee. I use it in my job as an Emergency Vehicle Technician. Fire Apparatus and Ambulances are sometimes equipped with AC Generators along with the necessary GFCI line voltage circuits. The GT-10GFI comes in real handy for testing/troubleshooting these systems. Greenlee Products have turned towards the import side lately. Their pliers, etc. are not made in the great U.S.A. anymore. This tester is not American made either but good luck finding one that is. It does the job though and the quality is better than most I have seen. As always Amazon.com came through with the best price!

It will go into small places okay, but the layout of the lights makes it difficult to use outside or on receptacles that are oriented vertically. Also, the lights are kinda dim.

Does it's job well. I've purchased a few of these since they're small and can easily get misplaced. Solid design. The white markings do start to wear off after a while of being pushed and shoved around in a tool pouch, but that's expected. Will more than likely be buying again.
