Greenlee Rules!
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!

Another high quality Greenlee product
Once again, great product by greenlee. I'm an hvac tech, but also get into electrical work. This works great for testing outlet wiring. For those who say the lights aren't bright enough, open your eyes... I have no problem seeing them light up. I love greenlee products, high quality.

Replaced my faulty one after 16 years of service.
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!
