Overview of the Logitech Signature M650 L and Logitech M171
The Logitech Signature M650 L Full Size Wireless Mouse is designed for larger hands, while the Logitech M171 Wireless Mouse is a more compact option suitable for various users. Priced at £34.97, the Signature M650 L is a premium choice, whereas the M171 is budget-friendly at £13.99. The differences in design, functionality, and user experience make each mouse appealing to different types of users.
Design and Comfort
When it comes to design, the Logitech Signature M650 L prioritises comfort for larger hands, featuring a contoured shape and a soft thumb area for extended use. This mouse is specifically tailored for left-handed users, making it a unique option for that demographic. In contrast, the Logitech M171 sports an ambidextrous design, making it suitable for both left and right-hand users. While the M650 L focuses on ergonomic benefits for larger hands, the M171's smaller size allows for easy portability and convenience, making it an excellent choice for users on the go.
Connectivity Options
The Signature M650 L offers versatile connectivity options, enabling users to connect via Bluetooth Low Energy or Logi Bolt USB receiver. This flexibility makes it compatible with a range of devices and operating systems, including Windows, macOS, and ChromeOS. On the other hand, the M171 utilises a plug-and-play connection through a USB receiver that connects in just three seconds. While both mice are compatible with multiple platforms, the M650 L's Bluetooth capability provides a more modern solution for users looking to declutter their workspace.
Performance and Functionality
In terms of performance, the Logitech Signature M650 L provides enhanced scrolling capabilities with its SmartWheel, which allows for both line-by-line precision and super-fast scrolling. This feature is particularly beneficial for users who work with lengthy documents or web pages. The M171, while reliable, focuses on straightforward navigation with controlled line-by-line scrolling and optical tracking. Its performance is sufficient for everyday tasks, but it may not offer the same level of advanced functionality as the M650 L.
Noise Levels
Noise reduction is a significant aspect of the Logitech Signature M650 L. It incorporates SilentTouch technology, resulting in up to 90% less click noise, making it an ideal choice for quiet environments such as offices or libraries. In contrast, the Logitech M171 does not specifically mention noise reduction features, which may make it less suitable for users who require a quieter working environment. The M650 L stands out in this regard, offering a more serene user experience.
Battery Life and Power Efficiency
The Logitech M171 boasts a commendable 12-month battery life, supported by power-saving features such as auto sleep. This longevity ensures that users can go longer between AA battery changes, making it a low-maintenance option. Conversely, the battery life for the Signature M650 L is not specified, which may leave potential buyers curious about its longevity. For users prioritising battery efficiency, the M171 is undoubtedly the better choice.
Customisation Options
Customisation is another area where the Logitech Signature M650 L excels. It allows users to customise the side buttons using Logitech Options+, offering shortcuts like back/forward navigation or copy/paste functions. This feature enhances productivity by enabling personalised control. The M171, while effective for general use, does not offer the same level of customisation. For users who value tailored functionality, the M650 L presents a clear advantage.
Price Comparison
Price is a critical factor when considering these two mice. The Logitech Signature M650 L is priced at £34.97, reflecting its advanced features and ergonomic design. In stark contrast, the Logitech M171 is priced at £13.99, making it an attractive option for budget-conscious consumers. While the M650 L offers several premium features, the M171 provides excellent value for those who need a reliable mouse without breaking the bank.
Which should you buy?
Choosing between the Logitech Signature M650 L and the Logitech M171 ultimately depends on your specific needs and preferences. If you have larger hands and seek an ergonomic design with advanced features, the Signature M650 L is an excellent choice despite its higher price. However, if you prioritise budget, portability, and straightforward functionality, the M171 is a dependable option that won't disappoint. Consider what features are most important to you, and select the mouse that best aligns with your requirements.
