Here's a short video that Brit Boy and I made to show you how it looks and sounds...
Yellow House video skills...yeah baby ;-) LOL
Anyway, the Sonic Keyfinder is very helpful and it's great fun too! One thing that I will share is that other sounds such as music, television, or background noise may activate it if they are comparable to your whistle. So don't worry if it goes off like that...it's normal and hey, you always know where your keys are :-) This has only happened to me twice and it was funnily enough set off by our laughter. I don't know what that says about my laugh or Brit Boy's laugh...I guess we'll chalk it up to both of us having "interesting" laughs ;-) We found this out when we were trying to make the above video. Never fear though...nothing else has set it off besides our whistles since then, so it's all good!
The Sonic Keyfinder comes with two extra batteries included and it's very easy to change the batteries. You just pop it open with a small screwdriver and slide the new batteries into the clips. Then you just snap it closed again. It's simple!
Christmas is coming soon, as you know, so if you're looking for a fun gift, this is one of the best stocking fillers out there for the very reasonable price of £2.99 (approximately $4.80 US).
Here's another video to show you some of the other cool things that you can find at Paramount Zone! Have fun looking around their site!
