    That package got out in time. It is well packaged. It’s easy to use just as displayed on the package. It has various quotes that tells you everything from reverse polarity to correct voltage, Including grounding faults. On the Bottom right of the tester There is also Built into the unit GC test facility, which is tested at 5 mA. I would highly recommend this, but both place and Usage simply it does what it says it does and with a clear Green lighted display.

    Does exactly what it is supposed to do.
    My home was built in 1985.
    Needless to say over time issues happen.
    This lead me to the issues and as far as I'm am concerned it helped to keep my home from burning down.

    As a sound and lighting company, we understand the importance of power in our work. However, it can also pose a threat to our equipment. To avoid any mishaps, we keep these units in our work vans for easy testing of outlets before plugging anything in. This also prevents any errors in using a meter.

    By simply plugging in the unit, it reads the voltage and indicates if there's a ground or if it's open. The device also lights up, making it easy to see in dark spaces or at night. I highly recommend these, not only for our fellow professionals but also for homeowners to ensure their homes have regulated power and avoid any potential damage to their equipment.

    Totally amazed with this tester. First let me say it came super fast and as described. At first I was a little concerned because the price was low. So it arrived today and I went straight to testing it. as a licensed electrician I had my doubts. So I plugged it into my house outlets. Knowing my outlets were wired correctly it did exactly what I should expect and tested correctly. Even shows the volts in a digital display. Now I went to my garage and on my bench tester I was able to create a situation that was incorrect wiring. And sure enough this tester caught each wiring issue I could throw at it. Also I do like how its constructed. It's small and fits right into my tool pouch. And also fits into my tool box nicely. For the price you cant beat it. And I've purchased mistakes in the past but this seems to be one of those wins. So if your on the fence about purchasing this item dont be. Buy it now while you can and while the price is still low.
