I did the same at every job for the last decade - either work buys an Ergo 4000 or I buy an Ergo 4000 and clear it with IT (honestly that was one place, I did it out of courtesy, I just took the new sealed in box to where IT sat and asked "ok if I use this?" and they said sure). These days I'm WFH forever and can use whatever the hell I want (work issues a stipend for hardware). The Ergo 4000 is such a large part of my computing experience that I have a stockpile of new in box units as a hedge against their eventual discontinuation. I've yet to have one die though, I wear the letters off fairly quickly but otherwise they are tough little beasts and easy enough to take apart and clean.
