Their system is easy to use, they are always willing to help when i have questions and their service is very reliable. I don't really like anything about them as far as this goes. They do an excellent job with registering domains but sometimes things get lost in translation or it takes just too long for me to get my hands on what i need at times. If you want an affordable solution that does not try to up-sell you like other registrars will then go see them. We were able to register 10+ subdomains without any problems once we had our DNS set up correctly.
