The Personal Anti-Lost alarm is a handy gadget that prevents you from losing your valuable things. The gadget comes with a transmitter and a receiver. Attach the transmitter onto the object of your affection, such as your pet, cellphone or even your GF. And have the keychain-like receiver in your hands or bag.
When the object is missing or just a couple of steps away from you, the transmitter will then turn on and alert the receiver, which then allows you to locate the object immediately. You can set a suitable alarm-triggering distance from 1m to 20m. This little device carries a price tag of $9.70, which is definitely worth of investment to ensure you won't lose your valuable things again.
