Pricing Comparison

The ProtoArc Wireless Mechanical Keyboard and Mouse is priced at £58.99, making it a more affordable option compared to the Logitech MK850 Multi-Device Wireless Keyboard and Mouse Combo, which costs £72.99. This £14 difference may be significant for budget-conscious consumers who are looking for a reliable keyboard and mouse combo without breaking the bank. Both products offer unique features, but the lower price of the ProtoArc might appeal more to users who need functionality without the extra cost.

Design and Build Quality

The ProtoArc features a durable aluminium construction that enhances its premium look and feel, while the Logitech MK850 includes a cushioned palm rest and a curved key frame designed for comfort during extended use. The ProtoArc's full-size 108-key layout comes with adjustable tilt legs for ergonomic typing, whereas the MK850 is built with familiar deep-profile keys that aim to support long typing sessions. Both designs focus on user comfort, but the choice between a lightweight, sleek design and a cushioned, supportive build may depend on individual preferences.

Typing Experience

In terms of typing experience, the ProtoArc uses low-profile mechanical red switches, providing a smooth and linear typing feel. This is particularly beneficial for users who prefer a quieter typing environment, although it may not be recommended for gaming. On the other hand, the Logitech MK850 is designed for all-day typing with its deep-profile keys and adjustable tilt legs, which can enhance comfort. The emphasis on customisation in the MK850, thanks to the Logitech software, allows users to assign 12 keys and buttons to their favourite shortcuts, potentially improving workflow efficiency.

Device Compatibility

The ProtoArc supports both 2.4G and Bluetooth connections, allowing users to switch between three devices seamlessly. It is compatible with various operating systems, including Windows and Mac. The Logitech MK850 also stands out in this area, offering compatibility with up to three devices and easy switching among PCs, laptops, tablets, and phones. Both products cater well to multi-device users, but the MK850 may provide a more integrated experience with its dedicated software for customisation.

Mouse Functionality

The mouse included with the ProtoArc weighs just 63 grams, which is designed to reduce hand fatigue during long working hours. It features three adjustable DPI levels, allowing users to customise cursor sensitivity based on their tasks. Meanwhile, the Logitech MK850's mouse is contoured for comfort with a soft rubber surface and hyper-fast scrolling, making it ideal for navigating lengthy documents or web pages. While both mice prioritise user comfort, the ProtoArc's focus on lightweight design contrasts with the Logitech's emphasis on precision control.

Battery Life and Charging

The ProtoArc keyboard and mouse come with built-in Type C rechargeable batteries, with the keyboard offering 500mAh and the mouse 300mAh. After just 2 hours of charging, the devices can have a standby time of up to 150 days, which is impressive for users who dislike frequent recharging. Conversely, the Logitech MK850 operates on two AAA batteries, which boast a lifespan of up to three years. While the ProtoArc offers quick recharging, the MK850’s long-lasting batteries may be more appealing to users who prefer not to charge devices frequently.

User Experience and Software

The ProtoArc focuses on providing a comfortable typing experience without extensive software features, making it straightforward for users who prefer simplicity. In contrast, the Logitech MK850 utilises Logitech Options software to enhance productivity, allowing users to link keyboard and mouse functionalities for smarter navigation. This added layer of customisation can be a significant advantage for users who rely on shortcuts and enhanced productivity features, particularly in professional environments.

Which should you buy?

Choosing between the ProtoArc Wireless Mechanical Keyboard and Mouse and the Logitech MK850 Multi-Device Wireless Keyboard and Mouse Combo ultimately depends on your specific needs. If you are looking for an affordable, lightweight option with a straightforward typing experience, the ProtoArc is a compelling choice. However, if you prioritise comfort, customisation, and long battery life, the Logitech MK850 is worth the higher investment. Both products excel in different areas, so your decision should align with your usage habits and personal preferences.
