I bought this for my wife, she is a teacher. There was an armed robbery near her school where the armed criminal tried to gain access to the school (luckily he was unable to get in). They had to lock down the school and with confidence my wife was able to throw on her back pack containing the insert and arm herself with her mace(unfortunately she’s not allowed to carry at the school). The insert gave her peace of mind and confidence. Well worth the money!
