These generations of wireless mouses are fine. The advantage, as small as it is, is less drag from the wire and not having to juggle with wires when working with a laptop. Given the batteries these days I’m fine with wireless.

Now I do not have the same view on wireless keyboards as these are pretty much stationary by default.

For me, the computer towers are across the room so I use cheap wireless battery mice and a nice wireless keyboard. I use rechargeable AA for the mice, and they last a pretty decent amount of time. I had a lot of rechargeable AA and AAA already. The keyboard has built in rechargeable battery and can swap inputs with a button press so I just have the one for the towers. If I turned off the backlight it would hardly ever need charging, but since I like the light, it needs a charge every few days of actual use.

For my laptop, which isn’t across the room, I still use a wireless mouse because I just have them. I can also have one mouse tethered to two dongles and use the same device for two PCs that I don’t have on at the same time, so I do that between the laptop and the gaming pc.

I switch mine (and my keyboard) between private PC (located under my desk because it’s cramped enough atop it, to the right) and company-issue laptop (placed atop it, to the left) when working from home. Like hell am I pulling the cable(s) out of my cable management to move it (them) over and move it (them) back, sometimes multiple times within the same day.

I’ve got my private headphones and my controller wired, but mouse + kb are keyed to the same dongle, which I proceed to move as needed. It’s a concession to convenience.

They’re also very efficient - I chronically forget to turn them off, but they still last so long that I was genuinely puzzled when the mouse started acting up and turning off until I noticed the blinking signal to indicate low battery. They’re not rechargeable, unfortunately, but I probably should see about getting rechargeable batteries.
