Passport came much faster than I was expecting; 4 days from them receiving my application. I payed for the 'mission critical' tier.
Yes, I could have made an appointment with the US passport service and traveled another city that had an office and handed in the application myself and saved a little money, but with the travel expense I doubt I would have saved much money, and with the convenience, this service was well worth it, to me.
These guys were the only expedited passport service, of the several I looked at, who actually picked up the phone when I called them and that gave me the confidence to go with them. They helped me along the way and answered all my questions. I would used the service again if I needed to in a heartbeat
