Tried multiple computers, multiple drivers, multiple ports. I reformatted my computer and installed a clean Win10. I was able to get the PC to recognize the key and the key would recognize the HRM and cadence sensor but then it would shut down after 15 minutes. After that it dropped out every 2 minutes. I'm pretty sure it's the key after replacing it with another brand and the key works (45 minutes straight!). I returned it with no problems but decided to buy another brand.
