Can’t find things? Sick of losing stuff? Well, not any more … thanks to StickR TrackR. This nifty little gadget will help you locate whatever’s lost in seconds using your smartphone. Just stick it on an item – it’s about the size of a large coin, so is fairly inconspicuous. Then, should you mislay it, you simply find out where it is using the TrackR app (Android and iOS), which will display the distance between you and your item. Easy, huh.

If this sounds like the sort of gadget you could use, we have three to win. To enter, fill in your details below and answer the question. The winner will be drawn from all completed entries.
