Computer mice: how to choose the best one in Portugal

Computer mice: how to choose the best one in Portugal

Buying a mouse seems simple… until you start comparing sizes , ergonomics , sensor , DPI , polling rate , Bluetooth vs. 2.4 GHz , weight, extra buttons, and shapes (classic, vertical, ambidextrous). The truth is, the “best mouse” is the one that fits your hand, your needs, and your environment.

DECO PROteste summarizes the first step in a very practical way: when choosing a mouse, confirm that its shape and size are comfortable , so you don't buy a mouse that's too small for large hands (or vice versa). And remember that a wireless mouse may require battery replacement.

In this guide, you'll find a clear method for deciding—whether for office , laptop , design , FPS , MMO , or mixed use.

1) Define your intended use (this determines 80% of the purchase)

Work / study / productivity

Prioritize:

  • comfort during long sessions

  • Silent click (if you work with other people)

  • Consistent accuracy (without "jumps")

  • Smooth scrolling (and, if possible, horizontal scrolling for Excel spreadsheets)

Gaming

Choose according to the type of game:

  • FPS (CS, Valorant, CoD): accuracy, low/medium weight, good form factor, good sensor, and stability.

  • MMO/strategy: more programmable buttons, good ergonomics for long sessions.

  • Casual: a balance between comfort, price, and a stable connection.

Mobility (laptop, travel, coworking)

Important:

  • compact size

  • Bluetooth multi-device

  • Autonomy and convenient charging

  • small 2.4 GHz receiver (if using dongle)

2) Ergonomics and size: the mouse has to "disappear" in your hand.

Rule number one is fit : a comfortable mouse reduces fatigue and improves control. DECO reinforces exactly that: shape and size should be comfortable for you.

How to validate in 30 seconds (without measuring anything)

  • Can you place your hand down without straining your fingers/wrist?

  • Does the thumb have natural support (without "hanging")?

  • Doesn't your little finger drag uncomfortably on the table?

  • Is the click easy and without any tension?

Important tip: If you experience wrist/forearm pain, consider an ergonomic/vertical mouse . Microsoft ergonomics guides describe how certain mouse shapes encourage a more vertical wrist posture, reducing pressure and strain.

3) Grip: palm, claw, and fingertip

Your grip influences the shape, height, and length of the mouse.

  • Palm grip: provides better hand support, comfort, and stability.

  • Claw grip: quick movements, arched fingers; balance between control and agility.

  • Fingertip: lighter mouse and shorter movements, less palm support.

Logitech explains that grip style affects control, precision, and speed — and helps in choosing the right grip format.
Corsair also details how each grip style changes the choice and performance, especially in gaming.

4) Sensor: Optical vs. Laser (and why it matters)

In high-precision gaming mice, the sensor makes a real difference. Logitech explains that gaming mice use optical or laser sensors ; laser sensors work on more surfaces, but can be more susceptible to jitter and acceleration, which reduces accuracy in competitive scenarios.

Practical recommendation:

  • For gaming/FPS and precision: a modern optical sensor is usually the safe bet.

  • For general use on various surfaces: laser can be useful, but precision reviews are confirmed.

5) DPI (or CPI): the number everyone sees... but doesn't always understand.

DPI (many brands also use "CPI") indicates how sensitive the mouse is to movement. It's not "better" just because it's higher — it's better when it fits your style, screen, and desk space.

The most important thing is:

  • to choose a comfortable DPI

  • Turn off unwanted "acceleration" (if you're looking for consistency)

  • Match it to your mousepad and sensitivity settings in the game/software.

A practical shortcut to get started:

  • Office/work: many people prefer mid-level and stable jobs.

  • Gaming FPS: Moderate levels (with a lot of consistency) tend to be easier for "muscle memory".

6) Polling rate (Hz): how quickly the mouse reports data to the PC.

This is where the feeling of "responsiveness" comes in. Logitech defines polling rate as the frequency with which the mouse sends its position to the computer; for example, 1000 Hz = 1000 times per second .
It also explains that higher frame rates may seem smoother, but they can increase battery consumption in wireless mice and slightly increase CPU usage.

Simple rule:

  • General use: 500–1000 Hz is typically excellent.

  • Competitive gaming: 1000 Hz is standard; anything above that is "fine-tuning" and depends on the setup.

7) Wired vs. Wireless (Bluetooth vs. 2.4 GHz)

DECO points out a practical issue: wireless mice may require batteries.
And there are still important differences:

  • Wired (USB): maximum stability, zero battery worries.

  • 2.4 GHz wireless (dongle): generally very consistent and fast.

  • Bluetooth: great for laptops and multiple devices; focus on compatibility and efficiency.

Regarding Bluetooth HID: technical documentation describes the HID profile as designed to provide low-latency connectivity with low power requirements.

8) Weight, skates and mat: the “feel” of the mouse

In gaming (especially FPS), weight influences:

  • fatigue

  • micro-adjustment control

  • speed of long movements

There is no such thing as a "perfect weight." The ideal weight is the one that gives you control without causing fatigue.

A mousepad matters more than it seems: it improves tracking consistency, comfort, and wear.

Final checklist (quick and smart purchase)

  • The mouse fits your hand (size/shape)

  • Compatible grip (palm/claw/fingertip)

  • Suitable sensor (optical vs. laser)

  • Balanced polling rate (1000 Hz is optimal for many cases)

  • Correct connection (cable/2.4 GHz/Bluetooth)

  • Clear warranty and terms (Portugal)

FAQ

What is the best mouse for working long hours?
A comfortable mouse in the right size, ideally with ergonomics that don't strain your wrist.

Does higher DPI mean better quality?
Not necessarily. Ideally, you want a DPI that gives you control and consistency.

Is Bluetooth suitable for gaming?
For casual gaming, yes. For competitive gaming, many prefer a wired/2.4 GHz connection for consistency (it depends on the mouse and the environment).
