I have a home inspection business and I bought two of those little GFCI
testers and they failed to trip the ground fault and I put that info
into my report but luckily I found out that the tester was faulty and
re-tested with another device before it was too late. With Harbor
freight it is hit or miss.


I had two of their GFIs trip but the front of the unit bulged out and was
unuseable. I guess it worked but I bought better ones when I replaced them.
