Hi Guys
My husband runs a security business ' Personal Security Company'.
Check out his website www.personalsecuritycompany.com.au
He supplies Personal Alarms to nurses and shiftworkers.
Have a look and see what you think http://www.personalsecuritycompany.com.au/collections/corporate-alarms
I carry the Keychain one with me on the job. Just makes feel safer.
Cheers
Amanda
