I worked on a short PR campaign for them. The one pro was that it was a good project to be on.
Cons
This was one of the worse PR clients I ever had. I was emailed almost daily and under pressure to deliver instant results. When that didn't happen I was accused of not doing any work. I was also expected to available basically whenever the person wanted. This was only a 5 hour a week thing and I felt like I was expected to be some kind of employee. At one point it seemed like I was being threatened with a bad customer review. I ended up quitting the project and putting out a cease and desist to block further contact. The treatment I received was very bad for my mental health.
