They are always willing to help you out with anything they can if it's not something we have already set up or done! I would say this product has been great for us so far because there aren't many things about them which do get old after using their service multiple times (if at all).
The only thing i dislike right now might be how long our videos load sometimes but other than that everything else seems good as well :) Great customer support from both sides - streamspread team & clients!! We use theirs mainly when uploading live streams of events/classes etc., where people need access straight away without having time delay between uploads like youtube does.
