Logitech Wave Keys MK670 Wireless Ergonomic Combo (Open Box)

I bought the Logitech Wave Keys Combo hoping for a seamless, ergonomic setup across both of my PCs. The keyboard delivers — soft keypress, well-contoured wave layout, and decent wrist support. I especially love the Easy-Switch buttons for toggling between computers (see photo — I labeled my machines “R” and “D” to keep things simple). But the mouse? A huge disappointment. It only supports one PC at a time, and it can’t toggle between Bolt receivers or pair with multiple devices. Despite being bundled as a combo, the mouse is basically locked to a single computer unless you unplug and re-pair it every time — which defeats the whole point of a multi-device workflow. I had to dig up an old Logitech M510 with a Unifying receiver to make this setup work. So now I have two mice on two pads, each marked for its own computer (again, see photo). The Logitech software (Options+, Unifying, etc.) was also confusing and failed to clarify which devices were supported by which receiver types. TL;DR: • ⭐⭐⭐⭐ Keyboard: Ergonomic, multi-device, comfortable • ⭐⭐ Mouse: Locked to one PC, no Easy-Switch, frustrating • ⭐ Software & support clarity: Poor If you only use one computer, you’ll probably love this combo. But for dual-PC setups, be ready to improvise — or spend more for a second Bolt-compatible mouse.
