The team at coppa are very professional in their work ethic & approach to working with clients/projects / people - they have always been great! I cannot think of anything that would make me dislike them or wish it was different from what we've experienced so far (which has all worked out well).
They're really good about getting back quickly when there's something you want changed after your initial approval etc., which can be frustrating but also makes sense as things change fast these days anyway without much notice given ahead time :).
