Very reliable, very service-oriented
The only app I've tested re: YouTube videos that does not run into serious trouble after a while when accessing the YouTube website. Moreover, when it seemingly did so once, SurFast staff was extremely helpful and responded very quickly (i.e. overnight) with advice as to possible reasons and where to look in my folder system for missing software components that might have been causing the trouble. Within 48 hours or so, the issue was solved. A very professional and service-oriented startup company.
