Don't buy into the sales pitch. At that range even bean bags can be lethal.

"A bean bag round can severely injure or kill in a wide variety of ways. They have caused around a death a year since their introduction in the U.S.[2] A round can hit the chest, break the ribs and send the broken ribs into the heart. A shot to the head can break the nose, crush the larynx or even break the neck or skull of the subject. This is why many officers are taught to aim for the extremities when using a bean bag round. A strike in the abdominal area can cause internal bleeding or strike the solar plexus which can disrupt breathing or heartbeat, but such a hit is generally safer than most other areas as well as presenting a larger target than an extremity. Fatalities are occasionally the result of mistaking other shotgun rounds for bean bags.[2] Activist Scott Olsen was struck in the head by a less lethal bean bag round, fired by a SWAT team member from the Oakland Police Department; he was incapacitated by the round, Olsen's skull was fractured by the round and his speech was impaired.[3]

"In 2013 in Park Forest, Illinois, an autopsy showed that a 95 year man had died from hemoperitoneum as a result of being shot by police with a bean bag gun.[4]"
