I like how easy they are to work with. The staff is personable and will go above and beyond to ensure all my needs are met. They have so many resources available to them that it's very hard to ask for something in a way that does not seem silly or stupid. Everything! We had a lot of issues with our old registrar, but they quickly got us set up with another one of their clients, who was able to help speedily. Their customer service is also great! Nothing really, I would suggest you get the most out of your experience by asking lots of questions. I am helping set up an LLC for myself and a couple friends, and having worked with several different companies over the years, this has easily been one of the best experiences.
