Design and Comfort

The ProtoArc EM11 NL Ergonomic Mouse is designed with comfort in mind, featuring an ergonomic shape that promotes a natural wrist position. In contrast, the HP 400 Quiet Wireless Mouse incorporates colourful silicone rubber in its design, making it both durable and easy to clean. While both mice aim for user comfort, the ProtoArc's extended wrist rest specifically targets ergonomic needs, potentially reducing strain during prolonged use. With dimensions suited for medium small hands, the ProtoArc may be preferable for users prioritising a comfortable grip, while the HP’s ambidextrous design caters to a broader audience.

Connectivity Options

The ProtoArc EM11 NL offers dual connection modes, allowing users to connect to up to three devices simultaneously via Bluetooth 5.0 and a 2.4G USB receiver. This versatility is particularly beneficial for users who frequently switch between devices. On the other hand, the HP 400 utilises Bluetooth and a 2.4GHz dongle, ensuring a reliable connection. However, it does not specify the number of devices it can connect to simultaneously. For multitaskers needing seamless transitions, the ProtoArc's multi-device capability stands out.

Battery Life

The ProtoArc EM11 NL features a rechargeable 500mAh Li-ion battery, which conserves energy by switching to sleep mode after 30 minutes of inactivity. This may be advantageous for users who prefer a rechargeable option. In contrast, the HP 400 boasts an impressive battery life of up to 24 months with just one AA battery, making it a low-maintenance choice. Users who dislike frequent charging may find the HP more appealing, while those who appreciate the environmental benefits of rechargeable batteries might favour the ProtoArc.

Sensitivity and Performance

The ProtoArc EM11 NL features adjustable DPI settings of 1000, 1600, and 2400, allowing for custom sensitivity based on user preference. This flexibility can enhance precision for various tasks, from casual browsing to detailed design work. Conversely, the HP 400 offers up to 6000 adjustable DPI, potentially providing greater sensitivity and adaptability across different surfaces. For users who prioritise high-resolution tracking, the HP may be the better choice, while the ProtoArc’s range caters well to everyday tasks.

Quiet Operation

Both mice emphasise quiet operation, but they do so in different ways. The ProtoArc EM11 NL is designed with a whisper-quiet click, helping users maintain focus in quieter environments. The HP 400's quiet clicks and scrolling options further enhance its suitability for shared spaces. This feature can be crucial for users who often work in cafés or offices. While both mice excel in this area, the HP’s broader range of quiet features may appeal more to those who value discretion.

Aesthetic Choices

The ProtoArc EM11 NL has a straightforward design focused on ergonomic functionality, appealing to users who prefer minimalism. In contrast, the HP 400 offers a more personalised touch with five colour options, allowing users to select a mouse that reflects their style. This aspect may attract those looking for a blend of functionality and aesthetic appeal. Ultimately, users who desire a unique colour palette may prefer the HP, while those who prioritise an ergonomic design will lean towards the ProtoArc.

Price Comparison

The ProtoArc EM11 NL is priced at £18.69, making it a competitively priced ergonomic option. The HP 400, at £19.95, is slightly more expensive but justifies its cost with features like extensive DPI settings and a long-lasting battery. While the price difference is minimal, budget-conscious buyers may consider the ProtoArc a better value given its ergonomic benefits. However, the HP offers a robust set of features that may justify its higher price for some users.

Which should you buy?

Choosing between the ProtoArc EM11 NL and the HP 400 Quiet Wireless Mouse ultimately depends on your specific needs. If ergonomic design and multi-device connectivity are your highest priorities, the ProtoArc is likely the better option. However, if you value quiet operation, extensive DPI settings, and the ability to personalise your mouse, the HP may be worth the extra £1.26. Both mice provide solid features, but your choice will hinge on whether comfort, connectivity, or customisation takes precedence in your daily computing tasks.
