I used the QQTube service for my company's social media accounts for the past 5 months. Initially, during the first 3 months, everything was smooth and satisfactorily. Along came 4th month and onwards when their deviations start popping up: Drops more than 5 or even up to 20 occur in every 2-3 days, some requests take more days than the usual to fill in the order etc. Then the worst came: they cannot resolve a consistent dropping of numbers from their delivery even if I had to report it to them repeatedly almost every other day. Such a waste of time and money! Not really worth signing up, better look for another which are more functional and reliable than this.
