Many of these combination products require a single premium payment, rather than many monthly payments or annual payments.  Some people purchase these products because there is a one-time payment and no chance of a future rate increase.  If you have a chunk of money that you are able to put toward a single premium payment you might consider a combination product, if you also need life insurance.  It would not be a good idea to purchase a combination product if you already have enough life insurance or if you do not have a need for it.
