Review on WETEN Rechargeable Self Defense Keychain Alarm - 130 DB Loud Emergency Personal Siren Ring With LED Light - Perfect SOS Safety Alert Device Key Chain For Women, Kids, Elderly, And Joggers In Pink by Steve Griffin

I bought one of these for my dad to use to get someone’s attention in the same house if needed after his hip surgery. So not so much for security purposes as for use as a sort or "call button” within the same house if, for example, he had trouble getting up and needed help but couldn’t yell loud enough for anyone to hear.The product seems good enough for this purpose but it doesn’t seem durable enough for security purposes. Hitting the pavement would probably break it and smashing it with your heel certainly would. Something used for security purposes really needs to be much more durable than this product.
