Arrrgh!
Logitech's worst quality for £70. Squishy membrane action, printed key legends that wear off, abs keycaps that wear out to a smooth shine in just a couple of years, disposable AA batteries, and the insidious Logitech Options software that is trying to shoehorn really bad, data-harvesting, telemetry-stealing AI with pretty dubious EULA terms right into keylogging driver software. NO THANK YOU. I support around 1000 users and the number of Logitech drivers causing bluescreens has gone from 0 prior to about 4 years ago to multiple incidents a month that are resolved by using older drivers or uninstalling Logitech Options entirely. Pointing devices and HID eventlogs pointing to the logitech driver, IRP conflicts causing bluescreens that directly blame the mouse driver on a bone-stock Windows 10 Pro install...
Logitech have successfully transformed themselves from a decent-quality peripherals manufacturer with functional drivers to a cheap peripherals manufacturer with bloated, over-reaching software full of problems.
To top it all off, this is "placebo ergo" - the science behind this shape is handwavey at best which is why it lacks the offset angle between left and right hands that all true ergo boards have (even Microsoft's) and also lacks any wrist rotation whatsoever. If this shape works for you, then great - but it's not a shape that is endorsed by any certified/chartered ergonomists. Logitech do have proper ergo keyboards with (and I quote them directly) "science-driven design" like the K860 and decades of past designs - which makes these cheap cash-grab wave keyboards all the more dislikeable.
