I like how fast my domain gets registered (2 days) compared with other registrars who takes weeks or even months for registering one single dotcom extension!!I wish there was an easy way to set-up additional subdomains once i purchase another main site using 1&1 servers since their price tag are quite high ($5 - $10 / month). There needs be some sorta integration between sites. You can't have 2 websites linked in different nameservers but pointing towards same IP address unless they use multiple CNAME records as well which means double cost per website. Easy-to use interface; great customer support - I called once for help with an issue in my domain setup (weirdly enough) only received quick feedback from them so they knew exactly how we should proceed next time.- Great pricing structure if used by multiple business owners/hosting companies within one organization or group as well has good integration into existing services like MailChimp & HostGator.
