Questions about Logitech Ergo K860 Split Keyboard for Business

The main difference between the Business and non-Business versions of the keyboard lies in the wireless technology used and the security features. The Business version uses Logi Bolt technology, which provides a more reliable and secure wireless connection, specifically designed for business environments with improved interference management and full FIPS-compliant encryption. It is optimised for cross-platform compatibility and secure connection only with the Logi Bolt USB receiver, which is not specified for the non-Business version. What's more, the Business version is explicitly presented as tailored to corporate IT needs, with features and ergonomic support similar to the standard version.

I assume you mean the Logitech Ergo K860 (CH, Wireless) variant (manufacturer number 920-009874) Exact specs can be found at https://www.logitech.com/de-ch.... The specs for 920-010347 can be found at https://www.logitech.com/de-at.... The cheaper model should come with Unifying receiver and the other (business model) with Bolt receiver. So the main difference should be in the transmission technology.
