Bluetooth trackers are really handy little devices that will stop you from losing your things - you can use them to find virtually anything, your phone, your keys, your wallet or even the TV remote.
Trackers connect to your phone via Bluetooth and will play a sound to help you find them, as long as you're in range, that is. Some go a step further than that and will be able to show you the last known location of the tag on a map if you're out of range. Others even use a network of devices to show you a real-time location. Long story short, they're super handy, especially if you're a little scatterbrained.
The Black Friday sales offer a fantastic opportunity to buy one or a few - Bluetooth trackers are always included in some of the best Cyber Monday deals as well.
