Comfort Keepers a keeper?

As a follow up to the previous post Is caring for the elderly a profitable business?, I’ve been looking at a few other elderly care franchises.  My preliminary favorite is Comfort Keepers. All the non-medical elderly care franchises have roughly a $25K franchise fee and 5% royalties. But, Comfort Keepers sets itself apart with its strong brand recognition, blanket coverage of the United States and internationally, and smart online marketing. Why not buy into a system with the largest network of referrals and strongest brand recognition?  With social and demographic trending in a favorable direction, and heavy referrals from its web site, and barring any show stoppers from their franchise agreement, I’d lean towards buying it.
