Good product and good service

Good thing, easy to use, very informative. I checked all the outlets in my house. All were ok except one with open ground. So, I can assume that this tester works.

Bought for a final check of electrical repairs during house closing walkthrough. Tester appears to be working as intended. Confirmed with known working outlets (normal and GFCI) prior to closing.

Does what it is supposed to do.

Very accurate.

I wish this device had been available even 10 years ago.

Works as described. Nice to see the voltage right there.

It was very accurate. Helpful gadget.

Accuracy? So far so good. LOL. Have only used it for testing outlets already in use to make sure polarity correct.

Practical and small.
