I really like this item! It will start to beep a few times if i whistled even when i hide it under my pillow. It's very sensitive, lightweight and a great value. Free Shipping takes only 12 days to reach Malaysia. I will sure to buy items from this website again.

a wonderful product especially for those old friends and family. you loss a thing, it will guide you through where to find it.

very nice and funny little thing

Very loud beep, so loud that my colleagues find them so iretating, that they keep my keys with them.
One whistle i kept in my locker, it reacts to EVERY whislte, music, etc...
Good as a prank, bad for headache

todo correcto

appena fischio lui suona e così non perdo mai le chiavi

just received the keychain, but it doesn't make a sound when i whistle and i do not know if i must do something different before it starts working.
I find something transparents sticking out from keychain, what's the use? how do we change batteries. but what i received is actually what is decribed. hope someone can assist with an answer.thank you.

now i got it! pulled away the transparent stuff, made a sound and it started beeping. much better when keys are attached. great for a gift.

very funny gadget....
thanks...

Its loud good looking and cheap, but too sensitive, beeps with other sounds not only whistles.
