For those of you that have a tendency to misplace your keys, now you can have a guard to keep with them at all times. Then if you happen to lose them, just give a little whistle. When the guard detects the whistle, he’ll give a yell back “I’m over here!”. With that, it’d make it a lot easier to find them or at least know that you’re in the correct general area. It’s not really something that would be good to own if you have a dog though. Every time you whistle for the dog, the little guy would be yelling. Which could be either entertaining or annoying, depending on your outlook. You can purchase the guard for £7.99 or about $13 from Thumbs Up UK.
