Replacement dongle for Razer viper ultimate

I had problems with the donlge working in my pc. So i switched it over to having the dongle in my charging dock. worked great until a few days ago.  It kept disconnecting an reconnecting every 3 seconds it seemed. Took the dongle out used the charging wire worked fine no issues afrer the disconnecting. Ive seen that there isnt any actual replacement for the dongle but it may be possible that someone can check the system to see if theres a replacement available. If thats something that could be done i’d appreciate it. Dont mind paying for a replacement. Thanks for your help.
