I have been using Gandi since around 2000. A few years back I was late renewing a domain and didn't get it submitted until the day of expiration - I had hours to spare. That, combined with delays in whois expiration data updates, made me very nervous so I phoned Gandi and...... I spoke to a real person! They were friendly and helpful! They told me no problem, not to worry. There is even a grace period of a couple weeks after expiration where you can renew without penalty.
I am now a loyal customer and it would take a lot for me to change. Saving a few dollars over ten years? Not a chance.
