Started out promising, failed miserably.
Triple started out promising. I was drawn by a "grand opening" special they were running where I believe domains were selling at $5.55 each. I didn't hear anything from them until I got a notice from DomainTools stating my domains had expired/changed owners. I attempted to login but mismatching SSL certificates and slow servers prevented me from renewing my domains. Fortunately no one picked up my domains when they dropped from the registrar, so I was able to register them again. Ultimately, I'm not satisfied and I advise everyone to steer clear of Triple.
