Grafton Tools Voltage Tester Non-contact AC Detector Pen, with LED Flashlight, Lifetime Warranty, On/Off Button, Batteries Included, Model GT-246AC (Misc.)

I purchased this because I live in an old trailer that seems to be having some problems with its outlets. So i wanted to see if all of them were working or if was my electronics or maybe i was putting too much on the breaker but with this voltage tester i tested my outlets and it was the outlets. Now i have replaced them and everything works fine. This is a wonderful product. The led flashlight is just a bonus.
I got this for free, I was in no way compensated for my honest opinion for this product.
