Samsung Galaxy SmartTag2 is now at its lowest price ever in Amazon's Black Friday sale

Bluetooth-trackers are a lifesaver for those prone to misplacing keys and other valuables, and even more so for parents whose kids have a habit of hiding essential items. These small devices can be easily attached to important belongings like car keys, purses or laptop bags and have quickly become a must-have gadget for many.

In an enticing Black Friday offer, Amazon has slashed the price of a popular Bluetooth tracker to its lowest price ever. The deal has seen the Samsung Galaxy SmartTag2 drop to £14 from the usual £38.99, a record low according to price tracker camelcamelcamel.

The SmartTag2 can be clipped on to valuable items or even pet collars to help find them if they go missing. Boasting a battery life of up to 500 days, it can be linked to the SmartThings app on Samsung Galaxy devices and features a Lost Mode, Search Nearby setting and Ring Your Tag option, reports the Express.

Shoppers are evidently smitten with the SmartTag, as one pleased customer said: "Most of all they do what they're designed to do. It's easy to see where the tags are on the Smart Things app."

Similarly enthusiastic, another user said: "I was concerned that there would be areas where there would be no response because of lack of Samsung devices. This doesn't appear to be the case."

A third thriller reviewer added: "So easy and simple to track anything – especially when you have someone little who likes to hide your house keys, no matter how high out of reach you put them. I cannot rate them highly enough. Have since purchased three more for teenage sons' keys and my car keys."

However, not everything is perfect according to some users, as one buyer pointed out compatibility issues: "I have returned this item as it isn't compatible with any other phone."

If you use an iPhone, you can pick up the Apple AirTag, which has been reduced to £28 from the usual £35. For those looking for compatibility across different smartphones, there's also the Tile Pro, which – despite its in-app purchases – is effective for tracking your belongings and is on offer at £24.99 for a pair.

Elsewhere, Debenhams has slashed £18 off the Silviano Chipolo Card Bluetooth Tracker at £32. Touted as 'the world's thinnest and loudest Smart Tracker', this device is compatible with devices running iOS 12 or Android 7 and later
