I used to sell their insurance back in the day (2001). They were such a fantastic company (both to their customers and to work for). And they have some of the most awesome supplemental insurance out there. Their cancer policy is their best. My mom bought their cancer policy and now she has breast cancer and she gets paid to drive to her appointments (so much per mile) as well as checks for certain things.
The great thing about them, I always thought, was that they put money in YOUR hands for you to spend however you wanted. They didn't pay your medical bills (although you could choose to use it for that if you wanted), they cut you a check based on the different types of coverages.
I no longer sell their insurance (because I pretty much did it to put myself through college), but I still wholeheartedly recommend them.
