Mouse Notes 02

The Shell

Introduction

  • Shell = the outer body of the mouse.
  • It decides shape, size, hump, material, coating + most of how the mouse feels in your hand.
  • Story: best running shoes in the world, but 1 size too small? You won't run faster, you'll just hurt. Mouse shell = the shoe.

1. Shape: Symmetrical vs Ergonomic

<- button split Symmetrical same both sides <- bulges right, tilted Ergonomic bulges for right hand
front (buttons) faces up in both sketches
  • Symmetrical: same on both sides. A 'safe' shape that fits most grips.

    e.g. Logitech G Pro X Superlight, Razer Viper V3 Pro, Pulsar X2, Lamzu Atlantis, G-Wolves HTS, Hitscan Hyperlight, Finalmouse UltralightX.

  • Ergonomic: shaped for your right hand. Super comfy IF it fits you.

    e.g. Zowie EC series, Razer DeathAdder V3 Pro, Logitech G502 X, Pulsar Xlite, Lamzu Thorn.

2. Hump Position (highest point)

front (buttons) is on the LEFT in these drawings back hump center hump front hump
the red dot marks each shell's highest point
  • Back hump: fills your palm -> good for palm grip.

    e.g. Zowie EC series is a classic palm-friendly shape.

  • Claw grip: base of the palm touches the BACK of the mouse, so a rear hump can suit claw too.
  • Fingertip grip: palm barely touches -> low + flat shapes, hump matters least.

    (rough guide - see Notes 09: Grip Styles)

3. Size

  • Length: front to back. The MOST important number.
  • Width: side to side, mainly where your fingers grip.
  • Height: how tall the hump is.

e.g. Zowie sells EC in sizes. Pulsar X2 has a Mini. Lamzu Atlantis has a Mini. Logitech Superlight = one size only.

Measure your hand:

  • length = wrist crease -> tip of middle finger
  • width = across the palm (no thumb)
  • note it down: "my hand is __ cm" - check it against the brand's size chart before you buy.

4. Weight (NOT only the shell!)

Weight = total of ALL parts added together. Biggest ones:

  1. shell (thick walls = heavier)
  2. battery (bigger = more hours, more grams)
  3. PCB + switches
  4. cable, skates, small parts

<50g ultralight 50-70g light 70-90g medium 90g+ heavy

Examples (approx.):

  • ultralight: Finalmouse UltralightX
  • light: Razer Viper V3 Pro (~54g), Logitech Superlight 2 (~60g)
  • heavy: Logitech G502 X (100g+), Razer Basilisk V3 Pro (112g)

(always check the brand's spec page before saying exact grams)

5. Materials (the car body story)

  • ABS plastic: everyday car. Cheap, light, most common. Can go shiny over time.

    e.g. most mainstream mice from Logitech, Razer and budget brands.

  • PBT plastic: premium sedan. Harder, more durable, resists shine.
  • Magnesium alloy: sports car. Very light + strong, but pricey, can feel cold/slippery.

    e.g. Finalmouse Starlight made it famous. Budget brands like Attack Shark now sell magnesium mice too.

  • Carbon fiber: supercar. Lightest + most expensive, still rare.

    e.g. Finalmouse UltralightX (carbon fiber composite shell).

6. Coating (the extra layer)

  • Matte / chalky: dry, stone-like feel. Most common, good grip.

    e.g. Logitech Superlight, Endgame Gear (chalky).

  • Soft-touch / rubbery: grippy + comfy, but can turn STICKY after a few years.

    e.g. old Razer DeathAdder Black Edition had rubberized sides.

  • Grip tape: stick-on rubber for extra grip.

    e.g. Razer includes grip tape with the Viper V3 Pro + DeathAdder V3 Pro.

  • Glossy: shiny + smooth. Looks premium, slips with sweat.

    e.g. Zowie glossy Divina versions.

  • No coating: raw plastic, often a light grainy texture from the mold.

Sweaty palms in Indian summers? Coating matters a LOT.

How coating wears out:

  • shine spots where fingers + palm rest
  • stickiness (rubbery coatings break down with sweat + heat)
  • peeling - starts at edges, button tips, side grips
  • discoloration on white mice
  • alcohol cleaners can strip matte coating -> use microfiber + a little distilled water

How to check if a mouse is coated:

  1. look at hidden spots: under skates, screw holes, the seam
  2. compare feel: coated = uniform, raw = slightly grainy
  3. worn spot feels different? -> a layer came off
  4. check the brand's spec page

7. Build Quality (plastic chair test)

  1. squeeze the sides -> any creak or flex?
  2. press the middle of the shell
  3. shake it near your ear -> loose side buttons rattle?

8. Where does Grip fit?

Grip belongs to the PLAYER, not the shell. But grip decides which shape + size feels right.

palm / claw / fingertip -> coming in the grip notes.
