I haven't had a chance to fully test this yet. I checked several circuits and the tests came back positive (I was the one who grew the circuits). I will be rewiring the circuits over the next few days to ensure this tester is accurate. I tested a few GFICs and they all ran fine. I haven't tested AFIC either. It can be seen that the construction is of good quality. So far I am very happy with my purchase. good price too.
