I use it, and a couple of my friend's have used it. I got the same result as I did with other tests. One of my friends seems to be accurately typed, and he says that's the first one he's done too. He scored as an ISTP... And the only thing I questioned was the S... I would have pegged him as more of an N, but maybe he's borderline on it.
I got INTP this time, when before I got INFP. My friends' impression of me is INFJ . I think the test is so-so....my ISFJ mom tests eNFp , and I think it's because of how the test is written.... A lot of Feelers I know test T on that test too.

I got INFJ or ENFJ on it, I think. My aunt got ENFJ but I highly doubt it. She's absolutely oblivious to how she comes off to other people. She bulldozes people and not in the smothering Fe way but in the name of "high efficiency".
