The interface is easy to use, it's very intuitive! I like also that you can register domains for free with them if they don't have your domain available yet (in my case). It took me some time before registering many of our websites because we had problems finding out what was wrong but then once found there were no issues at all so far as i'm aware anyway :) They are one in their support department - when helpdesk tickets come through its always been answered promptly by someone who knows exactly how things work or has gone into more detail than requested which helps enormously!! We're using registrardomains primarily due t othe great prices offered compared eith other providers suchas godaddy etc.
