Dimension comparison
Design and Comfort
When it comes to design and comfort, the ProtoArc Ergonomic Keyboard Mouse stands out with its split design and cushioned palm rest. This ergonomic setup promotes a more natural wrist position, making it ideal for long typing sessions. The Logitech MK955 Signature Slim Wireless Keyboard and Mouse Combo, while sleek and stylish, is tailored more towards users with larger hands and features a laptop-style keyboard without specific ergonomic adjustments. The ProtoArc's memory foam wrist rest offers additional comfort, which could be a game-changer for those prone to wrist strain.
Connectivity Options
Both the Logitech MK955 and ProtoArc Ergonomic Keyboard Mouse offer versatile connectivity options, but they cater to different user needs. The MK955 allows seamless switching between three devices, making it a great choice for multitaskers who frequently switch between a home desktop and work laptop. Conversely, the ProtoArc also supports connections to three devices but emphasizes its USB receiver and Bluetooth compatibility for easy transitions. While both products offer multi-device functionality, the MK955's ability to switch with a single tap could be more convenient for users who require quick transitions.
Typing Experience
The typing experience is noticeably different between the two models. The Logitech MK955 emphasizes a quiet typing experience with its SilentTouch technology, reducing click noise by up to 90%. This feature is excellent for shared workspaces or quiet environments. On the other hand, the ProtoArc provides an ergonomic typing experience through its split design, which is intended to reduce wrist tension. While the MK955 excels in minimal noise, the ProtoArc focuses on comfort and productivity, making it a matter of personal preference based on what users value more in their typing experience.
Battery Life
Battery life is another critical aspect where both products shine. The Logitech MK955 boasts an impressive battery life of up to 36 months for the keyboard and 24 months for the mouse, which means users can go for extended periods without worrying about recharging. In contrast, the ProtoArc's built-in 500mAh rechargeable lithium battery offers 250 hours of standby time after a full 2-hour charge. While the ProtoArc is rechargeable, the longer-lasting batteries of the MK955 may appeal more to users who prefer low-maintenance devices.
Price Point
In terms of price, the ProtoArc Ergonomic Keyboard Mouse is significantly more affordable at $76.98, making it about 30% cheaper than the Logitech MK955, which retails for $109.99. This price difference can be a decisive factor for budget-conscious consumers who still want a reliable keyboard and mouse combo. However, the additional features and build quality of the MK955 might justify its higher price for some users.
Compatibility
Compatibility is a crucial consideration for both products, and they cater to a wide range of operating systems. The Logitech MK955 works seamlessly with Windows, macOS, Chrome OS, Linux, iPadOS, iOS, and Android, providing versatile options for users with multiple devices. Similarly, the ProtoArc is compatible with Windows and Mac OS, along with Android devices. While both products cover essential platforms, the MK955's broader compatibility might be more appealing for users with diverse tech ecosystems.
Features and Customization
The Logitech MK955 offers customizable keys and shortcuts through the Logi Options+ App, enhancing productivity for users who rely on specific functions. This feature allows for a more tailored experience, especially for power users. In contrast, the ProtoArc focuses on ergonomic features and ease of use rather than extensive customization options. While the MK955's flexibility may attract users who need a personalized setup, the ProtoArc’s ergonomic design remains a strong selling point for those seeking comfort.
Which should you buy?
Choosing between the Logitech MK955 Signature Slim Wireless Keyboard and Mouse Combo and the ProtoArc Ergonomic Keyboard Mouse ultimately depends on your individual needs. If you prioritize an ergonomic design and comfort during long typing sessions, the ProtoArc is an excellent choice, especially given its lower price. However, if you value a quiet typing experience, extensive compatibility, and customizable features, the Logitech MK955 may be worth the investment. Each product serves its purpose well, catering to different preferences, so the decision hinges on whether you lean towards ergonomics or a more versatile typing experience.
