I called the number back ... it is "Safer Pass Technologies" ... at least that's what the recording says... "Thanks for calling Safer Pass Technologies, your call is now being directed to a representative .... " and I hung up.
STUPID SALES CALL, they call and hang up so you will call them back.
My opinion ---> JERKS FROM the Pits of HELL!   They might as well walk down the streets and knock on every door to sell their garbage!  If I wanted their product I would be looking for it.
