Very Handy Tools and Reasonably Priced

Would Recommend

If you are going to do any sort of Electrical Work around your house or elsewhere these two devices are very handy and valuable tools to help troubleshoot Electrical Issues. Best part is they are reasonable priced in today's world where prices are super inflated on almost everything.

Good but bulky

Used it to check the receptacles and GFCIs in my new house. Easy and straightforward My only complaint is it's too bulky to fit into some outside receptacles with covers.

Only worked once then failed.

Would Not Recommend

Worked once right out of the package. After that it wouldn’t turn on again even after putting in fresh batteries.
