They have been helping us with our social advertising campaigns for several years now - always doing an excellent job! I don't think there's anything that really comes up as much of problem when we work together (and it has already happened multiple times over). Sometimes they can be very slow at responding which sometimes leads into some confusion about what you're looking @ or trying achieve but overall great team & good communication skills- definitely recommend them!! The main benefit would just generally being able t get stuck solving problems more often than not because everything works so well between all parties involved :).
