Logitech Signature M650 L Full Size Wireless Mouse - for Large Sized Hands vs UGREEN Ergonomic Wireless Mouse

Design and Ergonomics

The UGREEN Ergonomic Wireless Mouse is purpose-built for reducing wrist strain with a 57° vertical grip, while the Logitech Signature M650 L Full Size Wireless Mouse caters to larger, left-handed users with a contoured shape. The UGREEN mouse promotes a more natural forearm posture, which can improve comfort and productivity over time, especially for right-handed users with hands longer than 17 cm. However, it is not suitable for left-handed users. In contrast, the Logitech Signature M650 L is designed specifically for larger left hands, featuring rubber side grips and a soft thumb area to keep the hand snug and comfortable during long hours of use. This difference means the UGREEN prioritises ergonomic posture mainly for right-handed users, while the Logitech mouse offers tailored comfort for larger left-handed users.

Connectivity Options

Both mice offer versatile wireless connectivity, but their options differ. The Logitech Signature M650 L connects via Bluetooth Low Energy or the Logi Bolt USB receiver, ensuring instant pairing and compatibility with multiple devices. The UGREEN Ergonomic Wireless Mouse supports Bluetooth and a 2.4GHz USB connection, allowing connection to up to two devices simultaneously—such as a desktop via USB and a tablet via Bluetooth. This multi-device capability can be a useful feature for users who switch between devices regularly. Logitech’s connectivity is straightforward with two primary modes, while UGREEN’s dual-mode and multi-device support adds flexibility, especially at a significantly lower price point.

Tracking and Performance

The UGREEN mouse offers 4K DPI precise tracking with four adjustable levels (1000, 1600, 2000, 4000 DPI), which is ideal for detailed work like CAD drafting and ensures accurate optical tracking even on glass surfaces. Logitech Signature M650 L does not specify DPI levels but focuses on precision scrolling, featuring a SmartWheel that allows switching between line-by-line precision and super-fast scrolling for long web pages. If you need fine tracking control and high DPI settings, UGREEN provides greater specification detail. However, Logitech’s mouse emphasises smooth, adaptable scrolling suited to general productivity and document handling.

Noise and Click Experience

Both mice feature quiet click technologies, reducing click noise by approximately 90%. This makes them suitable for quiet office environments or home use where noise can be distracting. The Logitech Signature M650 L uses its SilentTouch technology to minimise click sounds, while UGREEN’s mouse offers “Quiet Clicks” with a similar noise reduction. Both deliver tactile feedback without the loud clicking noise traditional mice produce, so neither has a distinct advantage here, making them equally good choices for noise-sensitive environments.

Button Customisation and Additional Features

The Logitech Signature M650 L provides customisable side buttons via the Logitech Options+ software on Windows and macOS, allowing users to assign shortcuts like back/forward or copy/paste, which can streamline workflow. UGREEN’s mouse includes six buttons, with next and previous buttons that offer convenience when browsing web pages or working. It allows connection to up to three devices and supports multiple operating systems, including Windows, macOS, Chrome OS, and Linux. While UGREEN focuses on multi-device functionality and six-button convenience, Logitech emphasises software customisation for enhanced productivity, which may appeal more to users who want tailored shortcuts.

Compatibility and Operating Systems

Both mice offer broad compatibility across multiple platforms. Logitech Signature M650 L supports Windows, macOS, Linux, ChromeOS, iPadOS, and Android, and is certified as “Works with Chromebook.” UGREEN’s mouse also supports Windows, macOS, Chrome OS, and Linux. Logitech provides slightly wider official compatibility including iPadOS and Android, which can be important if you intend to use the mouse with tablets or phones. Both mice cover the major desktop operating systems, but Logitech has a marginal advantage for multi-platform users.

Price and Value

The UGREEN Ergonomic Wireless Mouse is significantly more affordable at £12.27 compared to the Logitech Signature M650 L’s £34.97 price. UGREEN offers a specialized ergonomic design with multiple connection modes and high DPI tracking at roughly a third of the cost of the Logitech mouse. Logitech’s model is priced higher, reflecting features such as left-handed design for larger hands, SilentTouch technology, and software customisation options. Budget-conscious buyers looking for ergonomic benefits and multi-device connectivity might find UGREEN a compelling choice, while those needing left-hand specific comfort and customisation might justify the higher Logitech price.

Which should you buy?

Your choice between the Logitech Signature M650 L and the UGREEN Ergonomic Wireless Mouse depends on your hand orientation, ergonomic needs, and budget. If you are left-handed with larger hands and value a contoured shape with software customisation, the Logitech Signature M650 L at £34.97 is the better match. It also offers quieter clicks and broader platform compatibility, including iPadOS and Android. On the other hand, if you are right-handed, prefer an ergonomic vertical design to reduce wrist strain, want adjustable DPI up to 4000, and need to connect multiple devices simultaneously, the UGREEN mouse at £12.27 offers excellent value. Both deliver quiet clicking and wireless convenience, but their differing ergonomic focuses and connectivity options define their primary appeal.
