It does work, but setting it up on Apple devices is more awkward than advertised.
13 November 2017
Have tried both the Bluetooth LE and USB modes, both work fine (haven't tried NFC yet).
My main criticism of this device is the poor instructions. Pairing with an iPhone only worked when using the google smart lock app (which also means I can only use it for google on my phone). Pairing (Bluetooth LE) with my MacBook seems impossible as LE devices don't show in Bluetooth settings (despite the hardware, and third party apps supporting it). Had to connect the USB cable to use it. Overall it just seems that software support for Bluetooth LE is somewhat lacking on apple devices (obviously not Feitian's fault), but the instructions for this device clearly claim to support Apple devices. They should include instructions on how to actually use this device on those platforms, rather than leaving me to randomly search the internet for a solution.
