Updated August 2026 — full head-to-head comparison.
Design and Aesthetics
The Links9+ Wireless Keyboard and Mouse features a charming retro typewriter design, while the ProtoArc Ergonomic Keyboard Mouse focuses on functionality with a sleek ergonomic layout. The Links9+ has a vibrant coffee color that enhances its visual appeal, making it a stylish addition to any workspace. In contrast, the ProtoArc's gray and black color scheme leans towards a more professional appearance, designed to blend seamlessly into any office environment. The unique round keycaps of the Links9+ provide a nostalgic touch that may appeal to those looking for a distinctive look, while the ProtoArc emphasizes a practical approach to typing comfort.
Comfort and Ergonomics
When it comes to comfort, the ProtoArc Ergonomic Keyboard Mouse takes the lead with its full-size ergonomic design that promotes a natural wrist and forearm position. This design can significantly reduce wrist strain during extended use. The Links9+ offers a user-friendly experience with an optimal tilt to reduce hand fatigue but does not have the same level of ergonomic focus as the ProtoArc. For individuals who prioritize comfort during long typing sessions, the ProtoArc's cushioned palm rest and split design provide superior support compared to the Links9+.
Connectivity
Both the Links9+ and ProtoArc provide wireless connectivity, but they differ in their capabilities. The Links9+ uses a 2.4GHz wireless connection with a USB receiver that allows operation up to 33 feet away, offering a stable connection without the clutter of wires. The ProtoArc, however, is more versatile with the ability to connect to up to three devices simultaneously through USB or Bluetooth, which can be a significant advantage for users who frequently switch between devices. This feature allows for seamless transitions and enhanced productivity, making the ProtoArc a better option for multi-device users.
Battery Life
Battery life is an essential factor in choosing a wireless keyboard and mouse. The Links9+ operates on one AA battery for both devices, entering an auto-sleep mode after 10 minutes of inactivity to conserve power. The ProtoArc, on the other hand, features a built-in 500mAh rechargeable lithium battery, providing 250 hours of standby time after just a 2-hour charge. This means that while the Links9+ is less dependent on frequent battery replacements, the ProtoArc offers the convenience of rechargeability, which can be more economical in the long run.
Features and Functionality
The Links9+ is equipped with 12 Fn multimedia hotkeys that allow easy access to various functions like music and volume controls. This feature enhances user experience, especially for those who enjoy multimedia functionalities. The ProtoArc excels in functionality with its precision tracking mouse and adjustable tilt legs for better wrist positioning. Additionally, it includes forward and backward buttons for easier webpage navigation. While both products offer unique features, the ProtoArc's multifunctionality may appeal more to users looking for a comprehensive typing solution.
Price Comparison
In terms of pricing, the Links9+ is currently priced at $33.89, making it about 56% cheaper than the ProtoArc, which retails for $76.98. This significant price difference makes the Links9+ an attractive option for budget-conscious consumers who still want a stylish and functional keyboard and mouse set. However, it’s essential to consider whether the additional features and ergonomic design of the ProtoArc justify its higher price for your specific needs.
Compatibility
Both the Links9+ and ProtoArc are compatible with major operating systems, including Windows and Mac OS. The Links9+ is designed for a wide range of devices, including PCs and laptops, ensuring versatility across different setups. The ProtoArc also boasts broad compatibility, supporting Windows 7/8/10, Mac OS X 10.12, and Android 4.3 or higher. This compatibility makes both products suitable for users with varying technical setups, but the ProtoArc’s ability to connect with multiple devices simultaneously may offer an edge for those who use various platforms.
Which should you buy?
Deciding between the Links9+ Wireless Keyboard and Mouse and the ProtoArc Ergonomic Keyboard Mouse ultimately depends on your specific needs and preferences. If you prioritize budget, aesthetics, and are looking for a simple yet stylish option, the Links9+ at $33.89 is a compelling choice. However, if comfort, ergonomics, and multi-device connectivity are more important to you, the ProtoArc, despite its higher price of $76.98, may be worth the investment. Consider your typing habits and workspace setup to make the best decision for your needs.
