Logitech Unifying Receiver is basically rebranded, slightly-tweaked bluetooth from what I can tell. I've had a lot of them running in the same room together and not had a problem.

I have a ridiculously priced Topre Realforce, but when friends and family ask for a recommendation or I'm helping them setup a machine I would definitely recommend something like this if they're up for spending a little more. Historically I've been recommending the Logitech K840 in those scenarios. This looks like a wireless upgrade to that.

The Logitech Unifying Receiver uses an nRF24LU1+. They use a Nordic Semiconductor proprietary protocol, "ShockBurst".

This chip was pretty popular for non-bluetooth keyboard/mouse dongles, not just Logitech.

I found this comparison between that protocol and BLE https://d.lij.uno/misc-nrf24-ble.html it looks like the radios are very similar and can with some limitations be used for both, but the protocols differ

this does not use the old unifying received.. it use their new bolt receiver.. the two are not compatible with each other..

i don't know about the Unifying but the bolt is certainly based on Bluetooth, BT 5.0 Low Power to be exact..
