The ability to change WHOIS info in several different ways is my favorite feature of this service - I can update it manually or automatically using scripts so that someone else who does not have direct access into our system doesn't need me! Other people like their UI but dislike how slow they are about responding when issues arise with billing (which has happened many times). This was also one time purchase which makes us very hesitant as we do NOT want another bill for renewal if/when changes occur before then period ends. It's great because there aren't any bells & whistles included just what you would expect from an ISP-like product provider. We use them primarily internally only within corporate firewall where no external customers should be able see anything other than basic information such as email address etc., nothing more private at all.
