RF dongles almost always are Nordic Semiconductor parts and they use their proprietary (but open) protocol called Enhanced Shockburst. The minimum latency of BLE is 7.5ms (fastest connection interval in the spec) while ESB can be in the 100s of microseconds. Not sure about power savings but latency is better.

Not really, Logitech actually uses the LE PHY even for their "RF" protocol, at least since the Logitech Bolt controller which is what TFA is talking about. You can sniff Bolt traffic with a LE sniffer. > The minimum latency of BLE is 7.5ms (fastest connection interval in the spec) while ESB can be in the 100s of microseconds This makes for an average 4ms of latency, which matches what Logitech advertises. Then USB is then going to introduce 5-10ms at the very least...
