I left Allstate nearly 20 years ago after they failed to cover a theft loss of the factory stereo unit in an older honda civic we had used as a beater/commuter. (it had comp. on it)
I had roughly 10 years of paying into their system for cars/renter's insurance w/out a claim - haven't considered doing business with them for home-owner's or auto/boat insurance ever since.
as far as I know, nobody in my extended family inlaw/outlaw/blood relatives uses them either. they do suck. bad. as in like they'd use teeth and actually "blow" if they were giving a bj.
