Dimension comparison
Design and Ergonomics
When it comes to design and ergonomics, both the Logitech MK850 Performance and the ProtoArc Ergonomic Keyboard Mouse offer unique features tailored for comfort. The MK850 has a full-size ergonomic keyboard with a cushioned palm rest and contoured keys, which promotes a natural typing position. In contrast, the ProtoArc features a split design that helps position the wrist and forearm in a more relaxed posture. The keyframes of both products are designed to enhance comfort during long typing sessions, though the MK850 emphasizes a curved keyframe while the ProtoArc focuses on a split layout.
Connectivity Options
The Logitech MK850 Performance offers versatile connectivity options, supporting both Bluetooth and a 2.4 GHz USB receiver. This allows you to connect to multiple devices seamlessly, switching between them easily. It can pair with up to three devices, which is a similar feature found in the ProtoArc, where it also supports connection to three devices through USB or Bluetooth. The MK850, however, can be seen as slightly more advanced with its Logitech DuoLink software, enabling customized functionality between the keyboard and mouse, which enhances the multi-device experience.
Comfort Features
Comfort is paramount in both products, but they tackle it differently. The MK850 includes a cushioned palm rest and a full-size keyboard that allows users to type quietly and comfortably for extended periods. The ProtoArc, while also featuring a cushioned palm rest, incorporates a memory foam layer that offers additional wrist support. Both keyboards have adjustable tilt legs to help maintain a comfortable typing angle, but the MK850's design might be better for those who prioritize a traditional keyboard feel while still needing ergonomic support.
Performance and Usability
In terms of performance, the Logitech MK850 excels with its hyper-fast scroll wheel and efficient key design that allows for quick navigation through documents and web pages. The ProtoArc, on the other hand, features a 2000 DPI mouse, providing precise tracking and additional buttons for browsing convenience. Both products are designed to enhance productivity, but the MK850’s software integration may give it an edge in terms of usability and customizability for power users.
Battery Life
When it comes to battery longevity, the Logitech MK850 boasts an impressive battery life of up to three years for the keyboard and two years for the mouse, depending on usage conditions. In comparison, the ProtoArc's rechargeable battery has a standby time of 250 hours after just a two-hour charge. While the MK850's battery life is significantly longer, the ProtoArc's rechargeable feature may appeal to users looking for a more eco-friendly option.
Price Point
The Logitech MK850 is priced at $89.99, while the ProtoArc is about 17% cheaper at $76.98. Both products offer solid performance for their respective prices, but budget-conscious consumers might find the ProtoArc more appealing due to its lower price point. However, the additional features and battery longevity of the MK850 might justify the higher cost for some users.
Compatibility
Both the Logitech MK850 and ProtoArc are compatible with multiple operating systems, including Windows, macOS, and ChromeOS. The MK850 is optimized for these systems and supports seamless switching between devices, making it a versatile option for users who multitask across different platforms. The ProtoArc also claims compatibility with a range of operating systems, including Android, which may be beneficial for users who operate multiple devices, but the MK850's established reputation for cross-compatibility might give it an advantage here.
Which should you buy?
Deciding between the Logitech MK850 and the ProtoArc ultimately comes down to your specific needs and preferences. If you prioritize battery life, advanced software features, and a traditional keyboard feel, the MK850 might be the better choice despite its higher price. Conversely, if you seek a more budget-friendly option that still offers ergonomic benefits, the ProtoArc provides excellent value with its split design and rechargeable battery. Both products have their strengths, but your decision will hinge on whether you value premium features or cost-effectiveness more.
