Bluetooth tags are all very well when you want to keep track of wallets, keys and bags, but what about smaller devices? Or ones that don't have anywhere convenient to clip the tag? Chipolo's latest product may be worth looking at. The Chipolo Sticker is about the size of a paper clip and can be stuck to almost anything - sunglasses, headphones, remote control - but still has a loud alarm that will sound if you need to track down your missing item through the Bluetooth connected app. The battery is non-replaceable, although Chipolo will give you a 50 per cent discount on a new STicker when the battery wears out in about a year. Now there are no more excuses for losing things ever again. chipolo.net
