The customer service was excellent. This was my first project with crowdspring, and the customer service team answered all of my questions quickly. I also found the web interface pretty easy to use. I did feel a few people who submitted to the contest didn't read the brief, but I'm sure that happens here and there. Overall, people submitted great ideas, were into the project, and took feedback well. I didn't know there was the feedback service and I think that's excellent! Being about to collaborate with folks, explain why something worked or didn't led to better submissions. I chose a name that I love and am very happy.
