This company includes a contract online that goes on forever. You keep reading and its a lot of boilerplate legalize, but I warn you to read 100% of the contract because there are many traps in it, including obligating you for two years if you accept their promotional prices and subjecting you to a $299 cancellation fee. If you want an insurance certificate it's $19.95, and all sorts of added charges for various traps. Stay away from this company, they are poison. If your alarm goes off, You have to call them to cancel it rather than them calling you.
