The Cube Pro is our favorite key locating device. We love the settings and modes that the Pro offers, and during our noise analysis, we found it to be one of the most audible of all the Bluetooth models we tested. It has the option for disconnect notifications so that you'll know if you ever walk out of the house without your keys. The Cube app is top-notch, and they offer a desktop user interface that allows you to ring the device from a computer even if you aren't near your phone. We were also really impressed with its range when we took it into the field. We managed to stand 366 feet away from the device before the signal dropped. This particular model is also waterproof to a rating of IP67, which means that it can be submerged in up to a meter of water for 30 minutes. One of our favorite features of this tag, along with other Cube products, is how seamlessly they function with Alexa.
For this level of performance, you're going to have to pay a premium. The Cube Pro is one of the most expensive key finders we've seen &mdash; especially considering that the package only includes one device. It is also one of the heaviest models that we tested and will definitely bulk out your keyring. Bluetooth versions have many advantages, but they can also be kind of a pain. You'll need to download an app to a smartphone or tablet to set it up with this device. If you're looking for a bare-bones, easy-to-use model, this is not the one.

If having a cutting-edge app to accompany your Bluetooth tracker is a priority for you, take a look at the Cube Shadow. The Cube smartphone app works seamlessly with the tracker. A great feature is the "crowd find" community that will alert the user of a lost tracker location if another Cube user happens to come within range of the device. The Cube app works fantastically with Alexa. If you have an Alexa-enabled device, you can simply ask it to ring your wallet, keys, phone, or any item you've tagged with a Cube tracker. This manufacturer takes the app side of trackers a step further than most &mdash; in addition to a smartphone app, Cube also has a free computer app that allows you to see your trackers and your phone on an interactive map and activate alerts for either of them. We measured a volume of 79.3 decibels from two feet away, so hearing the alerts won't be an issue with this model. The Shadow also has an IP67 waterproof rating and is recharged using its included magnetic charging cable. 
Where the Shadow fell short was its range &mdash; we could only activate the alert tone from a maximum distance of 72 feet. We also found the shape of the device somewhat awkward. It's slim enough to fit in a wallet, but it doesn't have the exact dimensions of a credit card like other card-style trackers, so it may be a bit bulky for this application. There is also no way to attach it to a keyring, so you'll have to use one of the included stickers to attach it to an object with a loop or lanyard. Drawbacks aside, we recommend the Shadow for anyone looking for an Alexa-enabled Bluetooth tracker.

The Tile Mate has a long range, is quite loud, and gives you a better chance of finding your lost stuff than other non-Apple trackers.

The Best Bluetooth Tracker

The Tile Sticker is compact &mdash; with a disk shape and a diameter roughly the size of a quarter, it's ideal for sticking to just about any loss-prone belonging you can think of. Even with this model's miniature size, it produces quite a bit of noise with a measured sound pressure level of 72.8 decibels from 2 feet away. A perk of choosing a Tile brand tracker is the vast network of people using the community platform. When an item is lost, Tile will update you with a location if any other members of the platform come within range of your tracker, without notifying them. The Tile app also works with Siri shortcuts, so you'll be able to ring your lost items without ever lifting a finger. The Tile claims that the Sticker is waterproof, although there are no official ratings on their website or packaging.
The main flaw we found with the Tile Sticker is that you cannot replace the battery. Although the battery lasts for three years, once it's dead, that's it. Tile does, however, offer a subscription service that allows customers to send their trackers in to have batteries replaced. We find this to be inconvenient, considering other trackers are rechargeable or have replaceable batteries. On the subject of subscriptions &mdash; some of the Tile capabilities require the user to pay a monthly fee to enable any locked features. If you're going to purchase trackers from this brand, you should include paying for their services in your budget. But, once you get a Tile subscription, they're one of the best all-around brands.

In the world of credit card-shaped Bluetooth trackers, the Innway Card is the champion. This device offers the same simple setup as its cousin, the Innway Tag. We were able to stay connected to this device for a measured distance of 125 feet, which is significantly further than the other card trackers in our review. As with the other Innway trackers, the Card has a waterproof rating of IP67, meaning that it can be submerged in up to a meter of water for an hour before sustaining any damage. This model is also rechargeable, and it's so thin that you'll barely notice it in your wallet or purse. 
We aren't overly impressed by the alert volume produced by the Innway Card. Using a sound pressure level meter from a distance of 2 feet away from the tracker with the alarm enabled, we could only get a maximum reading of 61.5 decibels. If you'd like to rely on sound to find your items solely, we suggest choosing a model that emits a louder alert. Regardless, this is our favorite credit card-style model.
