Anyone use PSA DNA 7.95 service?

I'm going to try it out today for the first time only because I think I have a
seller jerking me around.  I dont know why the hell you'd sell fake autos of
duke snyder and John Morris and I dont see how it's worth the trouble for Dale
Murphy, but I think he is.  

So the question is have any of you used it and are they somewhat reliable?
