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…

The device looks great and is very easy to read Its handy to have the voltage readout right there on the unit

Very accurate.

Works perfectly.

works fine like any other outlet tester but has the plus of giving a voltage readout.

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.

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

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

Good product and good service

This little thing is smaller in person and I would highly recommend this. It is about the size of an outlet (appears a lot larger in the photos) tells you how much energy is going to each outlet. We have an older home with some outlets that are older, and it was helpful to be able to test that they were still safe in most aspects. Would recommend.

Handy tool for trouble shooting.
