We've had some good clients with them, I can't think off any specific ones at this point but they have been awesome to work for! They do great creative ideas that really turn out well in print ads etc., so it's not like just throwing something together when you're short staffed or whatnot - their creativity turns things into real assets instead (which makes me happy!).
Sometimes there isn’t always enough time before deadlines which has led us as partners/clients sometimes having our own projects come up during theirs because other people need help too quickly!! But overall very pleasant experience working alongside these guys over several years now :).
