Quick verdict
Choose the consumer M240 Silent when you want Bluetooth without occupying a USB port. Choose M330 Silent Plus when a plug-in receiver and its right-hand shape suit your setup. Both are basic quiet-click choices; keep a working mouse if neither connection nor fit is causing trouble.

Who should buy or skip
Buy if: your current mouse is noisy or poorly suited to the computer’s available connection.
Skip if: you need rapid switching between several computers, extra shortcut buttons or a gaming-focused mouse.
Compare the choices
| Choice | Choose it for | Main tradeoff |
|---|---|---|
| Consumer M240 Silent | Bluetooth and either-hand use | Requires compatible Bluetooth |
| M330 Silent Plus | USB-receiver setup and right-hand contour | Occupies a USB port |
| Existing mouse | No new expense when it already fits | Keeps any current noise or fit limitation |
Connection is the first filter
Logitech identifies the consumer M240 as a Bluetooth mouse with no dongle required. The M330 connects through its USB receiver. Check your computer before choosing: a USB-C-only laptop may need an adapter for the M330 receiver, while an older desktop may lack usable Bluetooth.
Do not confuse the consumer M240 with M240 for Business. Logitech’s business range has different connection and package details. Match the complete product name, not just the number, and avoid assuming an old Logitech receiver will work with a new mouse.
Hand fit matters more than a small price difference
The M240 is a compact, either-hand design. The M330 is sold with a right-hand-oriented contour. RTINGS’ M240 testing and an owner comparison both reinforce that a compact shape is a preference to evaluate, rather than a comfort guarantee.
Measure against a mouse you already like. If you have a large hand or dislike compact travel mice, a low price may not compensate for poor support. Left-handed use is a clear reason to inspect the shape carefully before buying M330. Neither model should be bought on a promise of curing wrist discomfort.
Quiet clicks do not make the entire workstation silent
Logitech advertises reduced clicking noise for these models. Treat that as a relative design claim, not a promise that the wheel, desk contact and every click are inaudible. Someone recording at a desk should consider microphone placement as well as the mouse.
Both checked product pages describe long replaceable-battery life, but actual life depends on use. The useful upgrade is a quieter or better-fitting daily tool. If you already have that, keep it. If you need device switching and shortcut controls, compare a different class of mouse rather than expecting these basic models to grow those features.
Buying in the United States or Canada
Check consumer-versus-business naming and that an M330 offer includes its receiver. Compare local return options for hand fit. Colour-specific discounts are useful only when the underlying model and package match.
The buttons open the named country’s Amazon search results. Match the exact model, size and included parts before ordering. Compare delivered cost, seller and return terms; no fixed price, availability or warranty eligibility is promised.
Questions before ordering
Does M330 use Bluetooth?
The consumer M330 Silent Plus discussed here uses its USB receiver.
Does Bluetooth mean multi-device switching?
No. Bluetooth connectivity alone does not establish a dedicated switching feature.
Final buying decision
Buy M240 for port-free Bluetooth and a compact either-hand shape. Buy M330 for a compatible receiver setup and right-hand fit. Keep your existing mouse when it already meets those needs.
