I have Bluetooth on laptops/desktops. But mobile device support seems lackluster. Also, relatively new phones (like my Pixel 3) can already act as their own security keys, making this product not the most useful. Bluetooth works with laptops/desktops; However, in my experience, it takes 5-10 seconds to connect and authenticate. I end up just plugging it in because it's actually faster. If you press the wrong key when trying to connect the plugin, you have to wait a good 10 seconds for it to stop before you can use USB authentication, this can be annoying. Very cool product, bluetooth connection takes too long, it might be better to get a Thetis dongle without bluetooth (great product too). EDIT 12/16/19: I've changed my rating to 5 stars. The bluetooth slowness seems more like a result of crappy bluetooth on my laptop and I've been using it more on my phone lately and it works really well with my phone. Connects much faster and fits the phone perfectly.
