Edit: Could be a fake BT5.0 adapter as seen here. Deal marked as expired but still available for purchase.
Very low price on this USB Bluetooth 5.0 adapter that will allow you to use Bluetooth devices such as speakers and keyboards etc. with your computer.
Ensure you select the "Color: V5.0 NO drive" as that's the cheapest adapter. According to the packaging the driver can be downloaded here so it's not necessary to pay extra for the driver CD.
