Doberman Laptop bag alarm
We are all scared of loosing our laptop because some one stole it. Now you can just hang this little device on your bag and just let someone pick it up 
They will not want to go far because a 100db alarm will sounds making you aware that your bag is gone or almost gone.
One little tip from me don’t forget to disarm it before you go somewhere with you bag.
