I dont know if they have improved, but 1and1's interface was quite annoying when I used them a few years back. And trying to contact them? Forget about it.
I'm very happy with dynadot. Good pricing, Great Services, Clean Interface. Sold.
Any experience with domain transfers (with either DynaDot or 1and1)?
1and1's entire interface is an unholy pain in the ass. I'm quite fond of DynaDot, actually, and switched to them as registrar of choice, transferring about 50 domains to them from assorted others and haven't had any problems.
i've heard good things about 1and1 as well, although i admittedly use godaddy because i only own a few names.
