Pros
good money for those who are willing to put their nose to the grindstone. That is the case with all jobs though. If you are willing to spend time on the doors, pounding the pavement, and you have good selling skills, you can make a killing of course.
Cons
the company allows a lot to slip through the cracks, you have to monitor every aspect to make sure you are paid correctly. It's hard sometimes to focus on selling when you have to be nervous about what happens on the backend.
