I'm a member of cz.cc domain name with VIP Level 2 for lifetime member which cost me $25. As VIP Level 2 I can registered 300 domain but one of my domain registered last year even.cz.cc was deleted even it's was free at first but then they change to premium domain and need to pay $4.95 per year, as admin said in their forum domain are free forever but not premium domain lists. form above link at at desk-help :- Now I'm banned for their forum and all my posted was deleted. What do you say about this type of business? scam!!! Beware of this free domain.
I used cz.cc for short period of time and it worked well except one thing, when you do whis lookup or alexa rank check it shows data for cz.cc, and not for yourdomain.cz.cc. Now, the better solution is co.cc, for sure, they're free and they're good!
Buy some of the tried-and high-quality domain com, net, org, info, biz ... GoDaddi has constant action discounts so that you will come out cheaper than to mess with this domain.
And the worst is that if he paid $25 for a membership (which means "domains" aren't free at all) he would better buy 25 INFO TLD domains, which extension sounds better than CZ.CC, specially if it was just for fun.
