This place is great... They are the nearest retailer to the chicagoland area for all Bates Devices or Lifesaver Bates Devices. Just be sure to call them as soon as possible to schedule getting your next bates device as ou must ship them bac nd forth every 30-60 days... To prevent from getting a $35 or $60 missed appointment fee be sure to call as soon as you see the read service light go on on your lifesaver bates devce. Hope ths was helpful...
