Just got a Razer Atheris and connected it via Bluetooth to my Surface Book 2 which all worked like a charm! Problem is when I brought it back out and turned it to bluetooth it won't connect to my computer. I have to remove the mouse from the computers bluetooth device and re-pair it every time! The mouse just shows the blinking blue indicator until I put it back in pairing mode and re-pair it. This is extremely frustrating.
