ROCK, INC  assistant is Always available. Whether via email, their dashboard interface, skype or over the phone, I never had an issue getting my tasks completed.  I tried to assign tasks at as odd hours as I could – they always completed the relatively easy ones (5-15 minutes of work) within ~45 minutes, often much sooner. Clearly, they are serious about providing round the clock service. 
ROCK, INC  assistant Consistent quality – again, provided the tasks are well defined 
ROCK, INC  assistant  - Better parallelization of tasks.  The first day, I basically tried to overload their system by giving them lots of research tasks that would have probably taken 2-3 days of a single virtual assistant’s time, or at least 1-2 days of my time. I had all my research back within 5 hours.
