Logitech M240 Silent Bluetooth Mouse vs Logitech MX Anywhere 3S Compact Wireless Mouse

Price and Value Comparison

The Logitech M240 Silent Bluetooth Mouse is significantly more affordable than the MX Anywhere 3S Compact Wireless Mouse, priced at £14.99 compared to £68.40 — a difference of £53.41, or about 78% cheaper. While the MX Anywhere 3S commands a premium price, its higher cost reflects advanced features like multi-device connectivity, an 8K DPI sensor, and USB-C charging. The M240 offers essential wireless functionality at a fraction of the price, making it ideal for users prioritising budget over performance. Despite being nearly 17 times cheaper, the M240 still delivers core reliability with up to 18 months of battery life and Bluetooth pairing without a dongle.

Design and Portability

The M240 Silent Bluetooth Mouse is explicitly designed as compact and travel-friendly, with a slim, ambidextrous build that fits easily in a bag. Its small size supports either hand naturally, enhancing comfort during extended use. In contrast, the MX Anywhere 3S is also compact but built for precision and ergonomics, featuring a contoured shape that suits right-handed users better. Both mice are portable, but the M240’s minimal profile gives it an edge in sheer portability. The MX Anywhere 3S includes a USB-C charging cable, while the M240 relies on standard AA batteries — a trade-off between convenience and long-term usability.

Connectivity and Compatibility

Both mice use Bluetooth for wireless connectivity, eliminating the need for a dongle. However, the MX Anywhere 3S supports connections to up to three devices simultaneously via Bluetooth, allowing seamless switching across platforms such as Windows, macOS, ChromeOS, and Linux. The M240 connects to one device at a time via Bluetooth, limiting multitasking flexibility. Additionally, the MX Anywhere 3S is engineered for Intel Evo laptops, ensuring optimised Bluetooth performance, which the M240 does not mention. This makes the MX Anywhere 3S better suited for users who switch frequently between multiple machines.

Performance and Tracking Accuracy

The MX Anywhere 3S boasts an 8K DPI sensor enabling precise tracking on any surface, including glass — a standout feature absent in the M240. This allows for subtle, high-accuracy movements, crucial for detailed work or design tasks. The M240 uses standard Bluetooth tracking with no mention of DPI specifications, suggesting it’s suitable for general productivity but less adept on unconventional surfaces. For users requiring fine control and versatility across diverse environments, the MX Anywhere 3S clearly outperforms the M240 in tracking capability.

Scroll Wheel and Input Precision

The MX Anywhere 3S features MagSpeed technology, enabling scroll speeds of up to 1,000 lines per second — the fastest and most precise scroll wheel available in this comparison. This allows rapid navigation through long documents or spreadsheets with minimal effort. The M240 does not specify scroll speed or mechanism, implying a standard mechanical scroll wheel with no advanced performance enhancements. Users seeking fluid, responsive scrolling will find the MX Anywhere 3S far superior, especially in data-heavy workflows.

Battery Life and Charging

The M240 promises up to 18 months of battery life using energy-efficient auto sleep, powered by two AA batteries. This longevity reduces the need for frequent replacements and aligns with eco-conscious usage patterns. The MX Anywhere 3S, while offering a shorter charge cycle (up to 70 days), supports quick charging: a 1-minute charge provides up to 3 hours of use. This fast-charging benefit is ideal for users who rely on their mouse daily and may forget to charge it fully. The M240 lacks a rechargeable option entirely, relying on disposable batteries.

Environmental Impact and Materials

Both mice incorporate post-consumer recycled plastic, reflecting Logitech’s sustainability efforts. The M240 uses 48% recycled plastic in its graphite version, while the MX Anywhere 3S uses 78% recycled plastic in the same colour — a notable advantage for environmentally conscious buyers. The MX Anywhere 3S also uses 61% recycled plastic in its pale grey variant, indicating broader commitment to sustainable materials. Although both models contribute positively to environmental goals, the MX Anywhere 3S demonstrates a higher level of recycled content across its range.

Which should you buy?

Choose the Logitech M240 Silent Bluetooth Mouse if you need a low-cost, reliable, quiet mouse for basic productivity tasks, travel, or secondary use. At just £14.99, it offers excellent value with 18-month battery life and silent clicks, making it ideal for shared workspaces or budget-conscious users. Opt for the Logitech MX Anywhere 3S Compact Wireless Mouse if you demand advanced performance: 8K DPI tracking on any surface, multi-device switching, MagSpeed scrolling, and USB-C quick charging. Though priced at £68.40 — nearly five times more expensive — it delivers professional-grade features tailored for power users, designers, or those working across multiple devices. The choice hinges on whether you prioritise affordability and simplicity (M240) or premium functionality and adaptability (MX Anywhere 3S).
