74 Tile Pro
Connect your keys to your gadget network with the best tracker around. Now twice as loud, and with twice the range of previous models, the Tile Pro also adds Alexa support; ask Amazon’s assistant to find your keys, and if they’re in Bluetooth range they’ll emit a loud noise. If you’ve lost your phone, on the other hand, just press the button on the Tile and it’ll ring. The battery should also last 12 months.
