If you lose something important, invariably it will happen at the worst possible time—say, your keys disappearing right before you need to leave the house, or you can’t find the remote and the big game is starting. Bluetooth trackers exist to help solve this exact problem, and now is a good time to pick up a bunch of them at a discount: A four-pack Samsung Galaxy SmartTag 2 is currently $44.99 on Woot, compared with $55.99 on Amazon.

The bundle includes four trackers. Prime members get free standard shipping, while everyone else pays $6, though the item does not ship to Alaska, Hawaii, or PO box addresses. Woot lists the deal as running for a little over three weeks or until it sells out, whichever happens first. Price trackers also suggest this deal is about as low as these trackers have dropped.

Each tag weighs less than half an ounce, and Samsung has redesigned the casing to include a larger metal-reinforced loop to make it easier to attach the tracker to bags, bikes, or a pet collar without needing a separate holder, notes this PCMag review. The SmartTag 2 uses Bluetooth Low Energy to connect to your phone when you are nearby, so you can trigger a ring to help track something down around the house. If the item is farther away, the tag can still show its location through Samsung’s SmartThings Find network, which uses nearby Galaxy devices to anonymously update the tag’s location. Some newer Galaxy phones also support ultra-wideband (UWB), which adds directional guidance on the screen, so you can walk toward the tracker once you are close.

The tag itself is IP67-rated, so it can handle rain, dust, or being tossed into a gym bag without much concern. Samsung also uses a replaceable battery that can last around a year, so you won’t need to replace the tracker every time it runs out of power. That said, the biggest catch is that this tracker is built for the Samsung ecosystem, given that it only works with Samsung Galaxy phones or tablets running Android 9 or newer, and it relies on Samsung’s SmartThings Find network. If you use an iPhone or another Android brand, this is not the right tracker for you (Apple’s AirTag works better for iPhones, while Tile Pro is a more flexible option for mixed-device households). For Galaxy users, though, the experience is simple, and the tracking network works well in busy areas.
