Very poor support, but low prices
The support really sucks at GoDaddy: The answer to a support request reporting a problem is: "there shouldn't be no problem". And so it continues, when you write back that there actually IS a problem... a second support agent will send a new answer, which is no more helpful than the first. Then there'll be a third and a fourth and a fifth support agent, Jim and Joe and whatever their names are, and it becomes more and more obvious that they don't even look into your issue and they simply keep writing silly messages, based on the general assumption that all users are idiots and that their system is infailable. During the whole process GoDaddy keeps pushing lots and lots of annoying advertisings even through the support emails, cluttering the entire thread with complete nonsense. The support system itself is quite poor aswell, being a mere email system, not web based.
The bottom line is, GoDaddy is lots of glitter and low prices, and it's quite nice as long as it works and you don't need any support. But if ever you should happen to have an issue and request support, you'll notice that they don't give a shit about your problem.
Therefore: I am going to move away, find myself another registrar, because I simply don't like the GoDaddy way of doing business anymore.
