Ruoshui Outlet Tester 48-250V, GFCI Tester CAT II 300V, Receptacle Tester with Voltage Display, Standard US Electrical Socket Tester with 7 Visual Indications for Home & Professional Use…

Practical and small.

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

Im an electrical contractor and have used it daily for several weeks now and have had no problems with it. Well see how it holds up compared to the ones Ive used in the past. Ive used some brand names testers and they just dont hold up to daily use.

Handy tool for trouble shooting.

It was very accurate. Helpful gadget.

Works perfectly.

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

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.

makes testing old outlets easy. Extremely easy to use and store.

Good product and good service
