Logitech M720 Triathlon Multi-Device vs Logitech Signature M650 L Full Size

Design and build quality

The Logitech M720 Triathlon Multi-Device features a sculpted design intended specifically for the right hand. It incorporates a rubber body to enhance grip during extended use sessions. In contrast, the Logitech Signature M650 L Full Size focuses on a shape that provides long hours of comfort. It includes a soft thumb area and rubber side grips designed to keep the hand snug. While the M720 is crafted for a specific handedness, the M650 series notes that sizes and handedness are available, offering potentially broader accessibility for different user preferences regarding physical fit.

Connectivity options

Both mice offer dual connectivity methods to suit different workstation setups. The M720 connects via Bluetooth or the wireless Logitech Unifying receiver. This receiver is notable for allowing users to connect up to 6 compatible Logitech peripherals with only 1 USB receiver, reducing port clutter. The M650 connects via Bluetooth Low Energy or the Logi Bolt USB receiver. Both options ensure reliable wireless performance without the need for constant charging cables, though the receiver technologies differ between the Unifying standard and the newer Logi Bolt protocol.

Performance

Scrolling performance is a key differentiator between these two models. The M720 features Hyper-Fast Scrolling, allowing users to fly through long documents and web pages with a simple spin of the mouse wheel. It includes an instant-stop feature and an option to switch to click-to-click scrolling. The M650 utilizes a SmartWheel that enables line-by-line precision for documents and super-fast scrolling for long web pages. Users can switch modes with a flick of the wheel. Both provide versatile scrolling experiences, but the M650 emphasizes the ease of switching modes for precision versus speed.

Ergonomics and comfort

Comfort is central to the design philosophy of both devices. The M720 is designed for endurance with a palm rest grip structure. It is explicitly crafted for the right hand, which may limit usability for left-handed users. The M650 emphasizes an upgrade in comfort with its specific shape and soft touch areas. The inclusion of rubber side grips on the M650 aims to prevent slipping and maintain a secure hold. Given the availability of different sizes and handedness for the M650, it may offer a more tailored ergonomic fit for a wider range of hand sizes compared to the fixed right-hand design of the M720.

Battery life and efficiency

Both mice are designed for long-term use without frequent battery changes. The Logitech M720 is designed for endurance with a 24-month battery life. Similarly, the Logitech Signature M650 allows users to work for up to 2 years on the single AA battery that comes with the mouse. This parity means that neither device holds an advantage in terms of power efficiency or maintenance frequency. Users can expect both devices to operate for approximately two years under normal usage conditions before requiring a battery replacement.

Software and ecosystem

Software customization varies significantly between the two options. The M720 supports Logitech FLOW, which allows users to move the cursor, text, and files across multiple computers. It enables easy switching between up to 3 computers or laptops with the touch of a button. The M650 supports Logitech Options+, available on Windows and macOS. This software allows users to customize side buttons to favorite shortcuts like back/forward or copy/paste. While the M720 focuses on multi-computer workflow integration, the M650 focuses on shortcut customization within a single system environment.

Price and value

When evaluating cost, the Logitech Signature M650 L Full Size is positioned at a lower price point of $39.99. The Logitech M720 Triathlon Multi-Device is listed at $44.99. Both devices offer 24-month battery life and wireless connectivity, but the M650 provides SilentTouch technology and SmartWheel features at a lower cost. The M720 justifies its higher price through its multi-device switching capabilities and Logitech FLOW support. For users who do not require control over multiple computers simultaneously, the M650 presents a stronger value proposition based on price and noise reduction features.

Which one should you buy?

Choosing between these mice depends on your specific workflow requirements. If you regularly switch between multiple computers or need to transfer files across systems, the Logitech M720 Triathlon is the better choice due to its Logitech FLOW support and 3-device switching capability. However, for most users prioritizing comfort, quiet operation, and value, the Logitech Signature M650 L is the recommended option. It offers significant noise reduction, adaptable scrolling, and a lower price, making it ideal for office environments or home setups where silence and ergonomics are paramount.
