Choosing a wireless mouse or keyboard starts with the link: a 2.4 GHz USB receiver or Bluetooth. Then come the key layout, the sensor resolution, click noise and power. This guide explains each line of the spec sheet and says which model suits which desk.
2.4 GHz USB receiver or Bluetooth
A 2.4 GHz mouse ships with a small USB receiver that is already paired. Plug it in and Windows picks up the mouse within seconds, with no setup. It also works in the BIOS and on the boot screen, which Bluetooth does not always do.
Bluetooth needs no receiver. It frees a USB port, which matters on a thin laptop with two ports or only USB-C. It works with an Android tablet or phone, an iPad or a Mac. Many desktop PCs, however, have no built-in Bluetooth: check before you buy.
| Criterion | 2.4 GHz receiver | Bluetooth | Wired |
|---|---|---|---|
| Setup | Plug in the receiver | Pair once | Plug in the cable |
| Uses a USB port | Yes | No | Yes |
| Tablet, phone | Rarely | Yes | Rarely |
| BIOS, boot screen | Yes | Not always | Yes |
| Batteries | Yes | Yes | No |
On a fixed desktop the receiver is still the simplest option, as on the Logitech M185 wireless mouse with its nano receiver. For a laptop and a tablet, the Logitech M196 Bluetooth mouse works with no receiver at all. The Rapoo M100 Silent offers both links and switches between three devices with one button.
Two things to know about receivers. On entry-level models the receiver is often paired with its mouse at the factory, so losing it means replacing the set. Pick a model that stores the receiver inside, such as the Xiaomi Wireless Mouse Lite. And if the pointer jumps, move the receiver closer: a nearby USB 3.0 port in use by a drive can interfere with the 2.4 GHz band. A front port or a USB extension cable fixes it.
Keyboard and mouse combos: one receiver
A wireless combo shares a single receiver between keyboard and mouse. Only one USB port is used, and both are paired out of the box. The wireless keyboard and mouse combos differ mainly in keyboard size and stated battery life.
- Logitech MK220: compact keyboard with a number pad, stated 24 months for the keyboard and 12 months for the mouse.
- Logitech MK270: full-size keyboard, 8 shortcut keys, spill resistant.
- Logitech MK235: full size, 15 function keys, keyboard rated at 36 months.
For a desk that never moves, a wired combo such as the Logitech MK120 removes batteries from the equation. All models are in the keyboard and mouse combo section.
AZERTY and Arabic: the key layout
In Morocco, PCs are set up in French AZERTY. A QWERTY keyboard set to AZERTY in Windows works, but the printed letters no longer match what you type. Check for French AZERTY on the product sheet, as on the Logitech K380 AZERTY Bluetooth keyboard or the wired Dell KB216.
Arabic is first a system setting. In Windows, add Arabic in the language settings, then switch with Alt + Shift or Windows + Space. If you type a lot in Arabic without looking at your hands, a keyboard with Arabic letters engraved next to the Latin ones helps a lot: the product sheet then says so.
DPI: what the number means
DPI (dots per inch) is how many pixels the pointer moves when the mouse travels one inch, or 2.54 cm. At 1000 DPI with no acceleration, moving the mouse 2.54 cm moves the pointer about 1000 pixels. On a 1920-pixel Full HD screen, about 5 cm of travel crosses the whole screen.
Higher DPI does not make a mouse more precise, it makes it faster. For office work, 1000 to 1600 DPI is enough. Most office wireless mice are rated at 1000 to 1600 DPI. A DPI button helps on a 4K screen: the HP X200 goes up to 1600 DPI, and the Essager 2.4 G offers 800, 1000 and 1600 DPI.
Silent clicks
A silent mouse uses damped buttons: you feel the click under your finger but barely hear it. That helps in an open office, a classroom, or late at night when someone is asleep in the room. The feel is slightly softer than a normal click, so try it if you click a lot. The Rapoo M100 Silent and the rechargeable wireless mouse with silent clicks are two examples. On the keyboard side, a low-profile model such as the Dell KB216 is also quieter than a mechanical keyboard.
Batteries or rechargeable
A mouse on one AA battery often lasts a year: that is the stated life of the Logitech M170, M171 and M185. The Xiaomi Wireless Mouse Lite, on one AAA, states about 4 months. A keyboard like the K380 states up to 24 months on 2 AAA batteries.
A rechargeable mouse saves buying batteries, but you have to remember to charge it. Models with a low-battery light or warning tell you before it dies. With batteries, switch the mouse off in your laptop bag, or it wakes at every bump and drains.
Gaming mice: polling rate and sensor
Polling rate is how many times per second the mouse reports its position. At 1000 Hz it does so every millisecond. A standard office mouse usually runs at 125 Hz, every 8 ms. The difference shows in fast shooters, not in a spreadsheet.
Maximum DPI matters less than sensor quality and shape. Many players use 400 to 1600 DPI. The Logitech G102 LightSync is rated at 1000 Hz, 200 to 8000 DPI and 6 programmable buttons. The Razer DeathAdder Essential offers 6400 DPI and a right-handed shape. Both are wired, like most models in the gaming mouse section.
Mechanical or membrane keyboard
A membrane keyboard presses on a rubber sheet shared by all keys. A mechanical keyboard puts a spring switch under each key. Typing feels crisper, travel is more consistent and the keys last longer: the HP GK100F is rated at 50 million keystrokes per key. The trade-off is more noise.
For gaming, look at anti-ghosting: how many keys pressed together the keyboard still registers. The HP GK100F mechanical keyboard switches between 6-key and 104-key modes. Other models are in the mechanical keyboard section.
The mouse pad
An optical sensor reads the texture of the surface. On glass or a very smooth varnished table, the pointer jumps or stops. A pad gives an even surface and protects the desk. An XXL size of 800 x 300 mm or 900 x 400 mm takes the keyboard and the mouse, on a rubber base that does not slide. For wrist comfort, the mouse pad with gel wrist rest keeps the hand flat. All sizes are in the mouse pad section.
Our advice
- Desktop PC, daily typing: a full-size 2.4 GHz combo with a number pad, such as the MK270 or MK235.
- Thin laptop with few ports: a Bluetooth mouse, or a nano-receiver mouse that stores the receiver inside.
- Laptop, tablet and phone on one desk: the K380 and the Rapoo M100 Silent, which each switch between three devices.
- Shared office or late work: a silent-click mouse and a low-profile keyboard.
- Gaming: a wired 1000 Hz mouse, a mechanical keyboard with anti-ghosting, an XXL pad.
- All day at the screen: a pad with a wrist rest, and DPI set so you cross the screen without lifting your hand.
