The Apple AirTag is undoubtedly the ideal device for tracking our objects or pets with great precision. However, there are other very attractive and cheaper options on the market, including the Eufy SmartTrack Link, which can currently be found on AliExpress with a discount of around 13.26 euros.

Buy the Eufy SmartTrack Link device at the best price

Although this Eufy Security device has a retail price of around 30 euros on AliExpress, it is currently over 50% off at a price of 13.26 euros. Plus, shipping is free and fast.

The Eufy SmartTrack Link is an object tracker that stands out as an excellent economical alternative to the AirTag device, fully compatible with the iPhone and Search Network. Thus, there is no need to download an external application, as in other models.

On the other hand, it comes with a hole that allows you to easily put it on a key or strap, thus forgetting to buy an extra case, and it has a forgotten or lost reminder that sends a notification to the mobile device, sending a note to warn that the object is no longer nearby.

And another feature to highlight is that it allows us to find our phone even if it is in silent mode, because if you tap it twice, it will start ringing.

We must add to all this that it has a QR code on the back which, when scanned, shows the contact information we set before starting to use it and that it is waterproof. It is powered by a CR2032 battery that is replaceable and capable of providing a year of autonomy.

Bluetooth finders

If you're one of those clueless people who forgets their wallet at home, lost their keys, or after turning on their cell phone search 2489 times a day, one day they're going to lose their minds, then a Bluetooth locator can help you keep track of your possessions by knowing their location in the moment. In this Bluetooth tracker buying guide, we review their most important features and suggest different solutions so you don't lose sight of your most precious items.

How do they work?

The operation of all Bluetooth trackers is very similar (be careful not to confuse them with GPS trackers, which are commonly used for pets), using Bluetooth Low Energy (BLE) to communicate with the mobile phone and thus, based on location data, know where it is.

The name leaves little room for surprises: this type of Bluetooth is named for its energy efficiency, which allows it to maximize the life of the battery it powers. For this reason, the autonomy is long, an essential feature to fulfill their function.

As long as the locator and mobile are within range, we can perform tasks to make it easier to find your current approximate location or call.

What happens when they lose connection? The range of Bluetooth is limited (Bluetooth 5.0 is approximately 240 meters), so if one of the two items goes out of that radius and stops seeing each other, then we can see what the last location of the tracker was.

They can lose the connection because the two devices move away or the tracking object's locator is lost, which is the time to activate the lost mode. In that case, it is common to receive a notification about his position if the network of compatible phones detects his presence, a process that happens anonymously.

How to Choose a Bluetooth Finder

- Action area: the greater the distance, the further you can be from the search engine without losing contact with it and therefore the more useful it will be to you.

- Network of compatible devices. Most Bluetooth trackers use other phones with the app installed to help them find lost objects by creating a network (a task that is done in the background and privately), so the more people use that platform.

- Although the locators offer the approximate location of the object in question, it is ideal to close the fence and know its exact location. For this refinement task, these devices use different technologies, including UWB or ultra-wideband, via the U1 chip in Apple's AirTags or Samsung's SmartTag+ (not yet available in Spain) and Tile which will soon be implemented on their devices, according to media outlets such as The Verge.

- Design and size. Ideally, a Bluetooth tracker should be as small and light as possible so as not to interfere with the object being tracked.
