That I can register domains for free, that I get to manage my own WHOIS information, that I can easily transfer domains from other registrars, and that I can access their customer service in multiple languages. They have a lot of features, but they're not always easy to figure out or use. Sometimes it's hard to find what you're looking for. It would be helpful if there were more tutorials, FAQs, and guides available online. The customer support has also been great. Their knowledge base is very thorough. I've never had any problems with them. I'm currently transferring some domains from another registrar.
