Lost Dongle for Razer Basilisk x Hyperspeed

Hi there,

recently I lost the dongle for my basilisk mouse, I've looking all over for a replacement razer 2.4 bluetooth dongle. I've only been able to find normal 2.4 dongles on places like ebay and amazon and it doesnt look like theres any support for razer with them. Is there anywhere to buy a replacement dongle?

Thanks for your time,
