I've been with them for over a year and had no hitch on it. I never request a support since all transactions went successfully. Pricing is great and the interface is clean.
Thumbs up here. Very good pricing and have had no issues. Been using them for about a year and a half. The only downside is their limited number of extensions they support. I have quite a few NNN.us names that I've had to keep at Dynadot due to this.
Good Service, pricing and free whois privacy make this company best in industry to use for domain name registration and thing that I like most the support of company for their clients at any time.
