What Each One Actually Is

| Price | ~$100 | ~$80 |
| Connectivity | Logi Bolt + Bluetooth | Logi Bolt + Bluetooth |

The MX Master 3S (Mouse)
The best all-day productivity mouse available. The MagSpeed scroll wheel lets you flick through long documents at 1000 lines per second, then snaps to precise-click mode for spreadsheet work. The thumb button cluster handles app switching, back/forward, and gesture shortcuts.
Who it's for: Anyone who scrolls a lot, works across multiple apps, or wants a mouse that does more than point-and-click.
The MX Keys Mini (Keyboard)
A slim, tenkeylessTKLTenkeyless: a keyboard with the numpad removed (~80% the width of a full-size board). Frees right-hand desk space for the mouse. Choose full-size only if you do heavy spreadsheet entry. wireless keyboard with per-key backlighting that senses your hands and brightens automatically. Keys have a satisfying low-profile travel — not mechanical, but far better than most laptop keyboards. The mini layout drops the numpad and cuts down width significantly.
Who it's for: MacBook users at a desk, multi-device switchers, anyone who wants a quiet keyboard that doesn't look out of place in a café.
The Pair Together
Logitech sells them as a combo (MX Keys Mini + MX Master 3S) and it's the most popular peripheral pairing for WFH Mac users. One Logi Bolt receiver, same Flow software, same Easy-Switch buttons (1/2/3 on both devices switch simultaneously).
Total cost: ~$180 for the pair, or ~$160 if you catch either on sale.
If You Only Have Budget for One
→ Prioritize the mouse. Most people are on a laptop keyboard that's tolerable. A better mouse (especially the scroll wheel) has a more immediate daily impact.
→ Get the keyboard first only if you're typing 5,000+ words per day and your current keyboard is causing wrist strain.
