Medical Mutual Protect Specified Disease Plan

Hi guys, I was just told about a catastrophic plan called Med Mutual Protect. I'm being offered a Specified Disease Plan with a $5K deductible $1 million calendar year benefit and $5 million lifetime benefit. This plan is just for major illnesses like CAD, Heart Attack, Stroke, Cancer, and etc. It is not accident related, although they also have a separate accident plan with the same amounts (5K deductible, $1 million calendar year benefit, etc.) Has anyone had any experience with these plans?
