Thank you match the picture with the product

Great value, I recommend it. Works like all the other North American outlet testers but includes a GFCI tester (just push the button and it simulates a ground fault, tripping the GFCI unit) *and* it includes an LCD Volt meter. We have both grid power and solar power and I like to know what the voltage is - this makes it easy, just plug in the tester. Beats dragging out the Fluke multi-meter and sticking probes into the outlet.

It knows more than the electrician.
