While they didnt support the specific type of YT video we were hoping to use, they had AMAZING communication with rapid on point responses. Tier 3 is definitely value for your money. CNAME feature you need to have a CloudFlare account, but they had really easy instructions to setup. We are keeping and waiting for them to implement update that supports our video. 5 Tacos! DomainLocking is account-wide not video specific. Also the player is super customizable. Def worth it!
