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…

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

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

Great product!!!

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.

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.

Does what it is supposed to do.

One thing I look for in measuring devices is their accuracy. When I received the tester I plugged it in and got a reading of 115 VAC. So checked it with two meters I own and they measured 120 VAC on both. I then looked up the specs on this tester and it stated + or - 2%. That would be 2.4 volts either way. It’s really no big deal but, it’s there. I just need to keep that in mine. Other then that, it’s larger then I thought which is ok. Easy to read the voltage and the red leds are bright. The GFCI function worked and the price is great. 4 out of 5 is ok. Update; since the accuracy was off by twice as much of the listed specification, I decided to return it. Of course Amazon made this pain free and the new one was still off, same direction but, slightly better. All and all, if your looking for voltage reading to be accurate, this model does not deliver. All other aspects work properly.

Works perfectly.

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.
