if you are serious about the domains you want to grab, DONT backorder with DomainMonster even if the backorder is free.
once i was trying to secure a .me domain, they faild by all means to secure it and some one else did with another registrar. so i opened a support ticket through the email asked them for a refund to my credit card not to my account. Guess what ? i got a reply after a week.
since that time, i moved my whole domains to godaddy. which is my main registrar .
so try to backorder the domain with different "domain catching services" but never come close to DomainMonster. the failure with them is 100% with no single doubt
