Pros
Unlimited income opportunity with residual income from sales which can pay out over ten years. One of the best overall product menus in the business, life insurance, disability insurance, group health, executive benefits plans, stocks and funds. MassMutual owns Oppenheimer Funds and uses MFS Funds which invesnted the mutual fund and was rated top overall fund family by Lipper for 2010. The training is excellent. Often there are redundant classes, which you may opt out of, but for the business it's a great advantage to be able to schedule your appointment times and still get training. The staff and support personnel are very experienced and can help you move your cases along.
Cons
The business is a sink or swim deal. You have to make enough cases the first three years to stay on your contract and there is no income if you don't sell product. You will be expected / required to work some long days.
