Introducing the ProtoArc EM11 NL Vertical Wireless Mouse
The ProtoArc EM11 NL is an innovative vertical wireless mouse designed to alleviate repetitive strain injuries (RSI) and discomfort linked to prolonged mouse use. Recently, I explored some premium ergonomic mice from Unimouse, but these specialized options can be quite expensive. So, what alternatives exist for those seeking ergonomic solutions to conditions like RSI and carpal tunnel syndrome without overspending? In this article, I delve into two new affordable ergonomic mice that aim to enhance cursor navigation while minimizing the risk of discomfort or injury.
ProtoArc: A Brand for Ergonomics
ProtoArc is primarily recognized for its diverse range of folding keyboards and portable mice. However, the brand also offers various ergonomic mice and input devices tailored for individuals who find traditional mice uncomfortable or challenging to use. Notably, ProtoArc even caters to left-handed users, who make up about 10% of the population, by providing specially designed left-handed mice.
The Features of the EM11 NL
The ProtoArc EM11 NL vertical wireless mouse features an extended wrist rest that comfortably supports the palm while encouraging a more natural and relaxed wrist and forearm position. This vertical design significantly reduces the likelihood of RSI and alleviates muscle tension, providing greater comfort during extended use. By rotating the wrist 90 degrees, the EM11 NL introduces an alternative method of mouse interaction.
Connectivity and Battery Life
This mouse offers flexible connectivity options, allowing users to connect via Bluetooth or a 2.4GHz wireless connection to up to three devices at once. Switching between synced devices is effortless, accomplished with a simple press of the mode button. The EM11 NL includes standard left and right buttons, a scroll wheel, a third button, and additional forward and backward buttons for easier web navigation. Unlike many traditional mice that rely on alkaline batteries, this model features a built-in rechargeable 500mAh Li-ion battery, charged with a USB Type-C cable. To conserve energy, the mouse enters sleep mode after 30 minutes of inactivity but quickly reactivates when moved. A low battery indicator alerts users when it’s time to recharge.
Adjustable Resolution for Precision
A standout feature of the EM11 NL is its adjustable resolution setting. The optical sensor can be configured to 1,000, 1,600, or 2,400 DPI, providing various sensitivity levels that are particularly beneficial for precise tasks like image editing or design work using programs such as Adobe Illustrator or CAD.
The EM01 NL Trackball Mouse
ProtoArc’s second ergonomic offering is the EM01 NL trackball mouse. Having used a Logitech trackball for years due to a severe RSI episode, I can attest to the comfort it provides. If you experience discomfort in your arm and shoulders after prolonged computer use, a trackball might be a suitable option for you as well.
Design and Usability of the EM01 NL
The ProtoArc EM01 NL features standard left and right mouse buttons, a scroll wheel, additional buttons for navigation, and two programmable buttons. Similar to the EM11 NL, this trackball mouse is compatible with Macs, although button customization is limited. This is unfortunate, as the EM01 NL resembles Logitech’s highly regarded MX Ergo S trackball. The EM01 NL supports two Bluetooth connections and can also connect via a USB-A wireless dongle for a 2.4GHz connection. Users can switch between devices using the third button located behind the scroll wheel. A unique feature of this trackball mouse is its clickable base plate, which allows for a 20-degree angle adjustment, making it closer to a vertical mouse—a potentially helpful feature for those suffering from RSI.
Battery Life and Maintenance
This model is equipped with a built-in 900mAh lithium battery, providing about a month of average use on a full charge. The EM01 NL also allows for adjustable resolution, offering five sensitivity settings: 200, 400, 800, 1,200, and 1,600 DPI. A trackball mouse can be especially advantageous for those with limited desk space, as it enables users to keep the mouse stationary and control the cursor with their thumb. However, it’s important to regularly clean the trackball and sensors, as dust accumulation can hinder responsiveness, leading to erratic cursor movement.
Pricing and Availability
The ProtoArc EM11 NL vertical mouse is currently available for purchase at ProtoArc and Amazon for a price of $26.99 / £34.42 / €17.27. Meanwhile, the ProtoArc EM01 NL trackball mouse is also available, retailing at $44.99 / £46.99 / €54.99.
