Useful and easy to use
Flashing red light and beeping(not an annoying one) when you whistle.After reading other reviews I was not sure about buying this but we tried lots of other sounds, clapping, coughing even screaming and the only sound that set the alarm off was a whistle, to turn off the beeping you just need to switch off at the side, then switch back on to activate it ready for the next whistle. Definitely worth the money, bought for my son who has to search for his keys 100 times per day before he leaves the house. Overall very pleased with the key finder, would recommend this if you need one.

Very sensitive
It works... a little too well.Wanted to use it to stop losing our remote. But tv shows set it off, coughing sets it off and the kids talking sets it off. Which makes me turn it off which makes it a bit pointless

Does what it says.
Bought for relative, however they find it too sensitive and it was working if someone just shouted into next room so they turned it off. Back to square one now with missing keys.

Utter trash didn't work asked for refund and have returned. Don't touch with a barge pole.
It didn't work was poorly made plastic didn't light up or react yo any whistles at pr or claps. Utter junk ypud get at a fair ground, but worse in the fact it didn't even work. Have sent back and am getting a refund.

Not a bargain!
It does not answer to whistles or claps every time, but tends to go off when the TV makes a loud sound! Rather annoying.

It is brilliant
It is a great item, my husband has not lost his keys since he has had it on them . And our grandchildren love it too , because of the noise it makes.
