Price Comparison

The Logitech MK345 Wireless Keyboard and Mouse Combo is priced at $32.75, while the Logitech MK850 Performance Wireless Keyboard and Mouse Combo costs $89.99. This means that the MK345 is about 64% cheaper than the MK850. If budget is your primary concern, the MK345 presents a compelling option without sacrificing essential features. However, the price difference reflects the additional functionalities and advanced design of the MK850, which may justify the higher cost for users who prioritize performance and comfort.

Design and Comfort

The Logitech MK850 is designed with ergonomics in mind, featuring a cushioned palm rest and a curved keyframe that allows for comfortable typing over extended periods. In contrast, the MK345 also offers a palm rest but lacks the advanced ergonomic features of the MK850. While both models include a full-size keyboard layout, the MK850's contoured keys and adjustable tilt legs make it a superior choice for users who spend long hours at their desks. If comfort is a priority, the MK850 stands out as the better option.

Connectivity Options

When it comes to connectivity, the MK850 shines with its dual connectivity options via Bluetooth and a 2.4 GHz USB receiver. This allows users to effortlessly switch between devices, including computers, tablets, and smartphones. The MK345, while offering a reliable 2.4 GHz connection, does not support Bluetooth, limiting its versatility in connecting to multiple devices. For users who need to work across various platforms seamlessly, the MK850 is the clear winner in connectivity options.

Battery Life

Both keyboards offer impressive battery life, but the MK850 takes the lead here as well. The MK345 boasts a battery life of up to three years for the keyboard and 18 months for the mouse. Meanwhile, the MK850 can last up to three years for the keyboard and an impressive two years for the mouse. This slight edge in battery longevity for the MK850 means less frequent replacements, which can be a significant convenience for heavy users.

Typing Experience

The typing experience on both models is designed for comfort, but the MK850's features enhance this experience further. The MK850's keys are crafted for a quieter and more comfortable typing experience, supported by a cushioned palm rest that provides additional comfort during long typing sessions. The MK345, although offering quiet operation, does not have the same level of key design sophistication. Users who often type for prolonged periods may find the MK850 to be a more enjoyable option.

Mouse Functionality

In terms of mouse functionality, the MK850 features a contoured right-handed mouse with a hyper-fast scroll wheel, allowing for quick navigation through documents and web pages. The MK345's mouse, while comfortable for all-day use, does not include the advanced scrolling capabilities of the MK850. Users who require enhanced precision and functionality in their mouse will appreciate the additional features of the MK850.

Compatibility

Both products are compatible with multiple operating systems, including Windows, macOS, and ChromeOS. However, the MK850's advanced multi-device capabilities allow it to connect to up to three devices simultaneously, making it ideal for users who frequently switch between different devices. The MK345, while versatile, lacks this multi-device functionality, which may be a crucial factor for those looking to streamline their workflow across devices.

Which should you buy?

Ultimately, the choice between the Logitech MK345 and the MK850 depends on your specific needs and budget. If you're looking for a budget-friendly option that still provides reliable performance, the MK345 is a solid choice at $32.75. However, if you value advanced features, ergonomic design, and enhanced connectivity options, the MK850 at $89.99 is worth the investment. For users who prioritize comfort, battery life, and multi-device connectivity, the MK850 stands out as the superior option.
