I used Vitalchek the 1st time in a rush to get my passport, which they delivered with out any problem. I wasn't fore warned about needed a notarized copy uploaded, but it wasn't a problem.
I had to have it rushed so I paid the over night shipping. the 2nd time I used them for my son's birth cert.
It was not a rush, but I did not find a cheaper option for slower shipping, so I paid the over night. that would be my only complaint, but the bottom line is they delivered and did it fast.
