Review by Jon Donnis
I went into this with a fair bit of doubt. Tracking tags have always sounded clever in theory, but I had never really trusted how well they would hold up in real use. So when the Xiaomi Tag landed in my hands, I decided not to go easy on it. This was going to be a proper test, not just a quick pairing and a glance at a map. I wanted to see if it genuinely worked as claimed, or if it was another bit of tech that looks better on paper than in practice.
Straight out of the box, things started well. I pulled the plastic tab from the battery and, within seconds, my phone had already picked it up. No fiddling, no repeated attempts, no digging through menus. It was, quite honestly, one of the easiest Bluetooth connections I have ever experienced. That alone set a strong first impression, especially for something aimed at everyday convenience rather than tech enthusiasts.

The real test came thanks to a friend heading off on a cruise to Norway. It felt like the perfect opportunity to push the tag beyond normal use. They did not install any app or connect to the tag in any way. All I asked was that they kept it in their bag throughout the journey. As they travelled by coach to Southampton, the tracking worked exactly as you would hope. Updates came through consistently, and the location data remained accurate as they boarded the ship and set off past the Isle of Wight.
Things got more interesting once they were out at sea. Anyone who has been on a cruise knows that connectivity becomes a different story entirely. Internet access is limited and usually comes at a cost, and my friend had no intention of paying for it. In theory, this should have limited the tag quite heavily. Yet, surprisingly, it still managed to report its location while in the middle of the sea. The way this works is that other passengers nearby had Bluetooth enabled and active internet connections, allowing the tag to anonymously piggyback on those signals. It is not foolproof. When my friend was in their cabin, with fewer people around, updates stopped. But out on the ship, moving among others, it worked far better than expected.

Once they reached Norway, normal service resumed. The tag provided regular and reliable location updates again, showing that it handles international travel without any real fuss. For something so small and lightweight, it proved itself more capable than I had anticipated.
Physically, the Xiaomi Tag is compact and easy to live with. At just 10 grams and roughly the size of two one pound coins placed side by side, it slips neatly into a bag or attaches to keys without drawing attention. The IP67 rating adds a layer of reassurance, especially for travel, and the use of a standard replaceable battery is a practical touch. Claimed battery life sits at over a year, which I could not fully verify in this test, but the ability to swap batteries easily removes most of the concern anyway.

In day to day use, it makes perfect sense for items you are likely to misplace or travel with. Suitcases, handbags, rucksacks, even keyrings. The integration with both Apple Find My and Google's Android tracking network gives it a wide reach, and the option to share access with family or add contact details for lost items adds a bit of thoughtful functionality.
There is, however, one clear limitation. The entire system relies on Bluetooth and nearby devices. If there are no phones around with Bluetooth enabled and an internet connection, the tag cannot report its location. That is simply how this type of technology works. In reality, it is less of an issue than it sounds, given how many people carry smartphones with Bluetooth switched on, but it is still something to be aware of. Foe example if you are in the middle of the desert and your phone has died, the tag cant report its location to anyone who you have shared the app with, although it can report its last known location, so there is that. So people, don't go off to the middle of the desert on your own!

What stands out most is just how well the Xiaomi Tag handled a genuinely unusual test. Being tracked across countries and even in the middle of the sea is not exactly standard use, yet it still managed to deliver. That alone says a lot about its reliability.
At £12.99 for a single unit, or £44.99 for a pack of four, the value is hard to ignore. It does what it promises, it is easy to use, and aside from the inherent limitations of Bluetooth-based tracking, there is very little to complain about. I started this review as a sceptic. I did not finish it that way.
A big thanks to Xiaomi for sending me the tag to review, I just need my friend to finish his cruise and give me the tag back. Lets hope he doesn't get lost, or I will be the only one who can find him!
