I've been reading about these key finders for a long time and wanted to get one as I'm a frequent flyer and wanted something to keep on my hand luggage just in case it gets lost or stolen so I can track it's November's and know exactly where it is so I can find it. The key finder comes very nicely packaged up and also you download an app to use with it that works perfectly. I have tried it out I got my friend to take it away and then I havld to track it using he app and it works flawlessly would definitely recommend this.
