"Life Line Screening"- Your opinion on this service?

My Mother recently turned 81 years old. She received a pamphlet or flyer in the mail from Life Line Screening, based in Cleveland, OH, offering Stroke/Carotid Artery Screening, Abdominal Aortic Aneurysm Screening, Peripheral Arterial Disease Screening and Osteoporosis Screening via a mobile unit all for the low price of $129.00. Is this legitimate? Is this a waste of her time? I checked the service out on the internet and it seems legit to me. Thank you for your help.
