Direct support from 99designs was really impressive, they were happy to answer my silly questions and provided me with good advice on how to proceed with my first contest. The site was easy to use and provided a great facility for feedback and collaboration in the form of annotations which I used quite heavily.
Product : I was overwhelmed with the number of designs submitted (close to 100). The designers I met were very friendly and also left me quite positive feedback which was great. I am very happy with the final design and will most certainly be using this service again.
