Logitech G305 vs M575S: Move the Mouse or Roll the Ball?

Choose G305 to keep moving the mouse, provided its USB receiver setup fits. Choose M575S for stationary thumb steering, with direct Bluetooth or its included Bolt receiver. If you require both conventional mouse movement and direct Bluetooth, neither selected model establishes that combination.

The buying question

Can your preferred pointing action and connection method fit in the same device?

G305 pairs moving-mouse control with its dedicated receiver. M575S pairs stationary thumb steering with Bluetooth or Bolt.

Quick verdict

When to skip: You require conventional mouse-body movement and direct Bluetooth together.
When the recommendation changes
  • A direct-Bluetooth requirement favors M575S only if thumb steering is acceptable.
  • If body movement and direct Bluetooth are both mandatory, look beyond this pair.
  • If both receiver setups fit, the pointing action can decide.

The differences that matter

Pointing Action

Logitech G305 LIGHTSPEED (Black)

Move the optical mouse body over a suitable surface.[1, 2, 3]

Logitech ERGO M575S (Graphite + Blue Ball)

Roll the thumb ball while the body stays in place.[4, 5]

What this changes: Choose G305 to retain moving-mouse control. M575S removes the mouse-sweep requirement, but you must want thumb steering and have room for its body and your hand.[1, 2, 3, 4, 5]

The better fit depends on your priorities

Host Connection

Logitech G305 LIGHTSPEED (Black)

The documented connection uses the included LIGHTSPEED USB receiver and requires a USB 2.0+ port. Connect directly or through the receiver extension cable.[2, 3]

Logitech ERGO M575S (Graphite + Blue Ball)

Direct Bluetooth or the included Logi Bolt USB receiver.[5]

What this changes: M575S can leave a USB port free on a compatible Bluetooth host. G305 fits when its dedicated receiver setup is acceptable. If both receiver routes suit your computer, choose by steering action.[2, 3, 5]

The better fit depends on your priorities

Direct Bluetooth is essential

The better fit depends on your priorities

Choose M575S if thumb steering also suits you. If you require body movement, choose another model with both requirements documented.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

A lower price cannot fix the wrong steering action or an unsuitable connection. Compare offers only after both requirements fit.

There is insufficient verified price history here to recommend buying now or waiting.

Limitations

  • Neither product was tested hands-on. No comfort, health, accuracy, latency, gaming, reliability or endurance advantage is established.
  • This comparison covers US G305 910-005280 and M575S 910-007027. It does not transfer older M575 specifications to M575S.
  • Check your exact host and current software support before buying. The connection choices do not guarantee every operating system, customization feature or receiver interchangeability.

Questions shoppers ask

Does choosing M575S change the battery routine?

Both selected models use an AA. The M575S guide also says recharge, conflicting with its battery-door and single-AA description and the exact product data listing an included AA. Plan for AA replacement; that sentence does not establish built-in USB charging or a new rechargeable revision. Its cause is unconfirmed.

Can I choose G305 just because my computer has Bluetooth?

Plan around its documented LIGHTSPEED receiver connection. The technical specification identifies Logitech’s 2.4 GHz protocol and a USB-port requirement; the setup guide directs you to connect the receiver. A computer’s Bluetooth capability alone does not fulfill that documented setup.
