Pros: Low price

Cons: Seems to work with random sounds and not just by whistling

Bottomline: It's a low priced gadget and a useful one for those who keep losing their keys (or even their pets). Seems though that it's activated with random sounds and not just by whistling and it gets really frustrating after a while. (Posted on 5/10/12)

Bottomline: Fantastic product! Segít megtalálni az elveszett kulcsokat. (Posted on 5/7/12)

Nice, easy to wear, easy to use, sometimes too easy. Let me explain. The keychain is triggered too easy. It's too sensitive. When I pull my keys out it triggeres (when a key hits it), it triggered almost every time when my baby cried, and when cat was meowing for food. And when I raise my voice also :/

But the battery still holds. In the end it's better to be too sensitive than to be not sensitive enough. Thing is, it triggers about once every hour, so I know where my keys are all the time. LOL!


Pros: battery life, not too silent, easy to use, good plastic (won't break easily)

Cons: too sensitive sometimes

Bottomline: Nice product. Better having it than living without it (Posted on 5/6/12)
