Pros
The atmosphere and support system is great. Both the RVP's and mentors do a great job giving you the help that you need (including my long distance mentor, the famous Michael Balush). The money making potential is there if you commit yourself to your job. The ability to grow and be promoted depends on how hard you work. I was with Power for a little over a year and was promoted from marketing to a management position to a sales consultant role. The trip to Mexico was awesome.
Cons
The hours for marketing can be long, but the more you walk the more $ you make. The sales hours are unpredictable and you are not given gas reimbursement. You are expected to work 6 days a week as a sales consultant. Management is very up front with all of these cons, so you know what you are getting yourself into.
