I’ve been trying to find a way to contact Razor for a replacement Dongle. My friend gave me his old Nari Ultimate since he didn’t use it much, but He doesn’t remember there being a USB. But the box has the dongle model number and says it is pc compatible with USB. 
 

Is there any way I can get a replacement? I know it’s an older pair, but it works for me. I just cannot change any of the settings/ use it on my PC.
