Reduce Wrist Strain, Boost Productivity
ProtoArc EM11 NL Wireless Ergonomic Vertical Mouse in Black is designed for comfort during extended computer use. Its 58° vertical angle promotes a natural handshake position, reducing forearm and wrist strain. This mouse connects to up to three devices simultaneously using Bluetooth 5.0 or the included 2.4G USB-A receiver, offering seamless switching between your PC, laptop, or tablet. Imported for Indian buyers, it ensures authentic quality and performance.
The built-in 500mAh rechargeable lithium-ion battery provides long-lasting power, easily recharged via the Type-C cable. With adjustable DPI levels of 1000, 1600, and 2400, it offers precise tracking for various tasks. The silent click buttons allow for focused work without distraction, while the ergonomic design aims to improve productivity and comfort over standard mice. Compatible with Windows, macOS, and Android systems.
Experience a smoother workflow with the ProtoArc EM11 NL. While there's a brief learning curve to adapt to the vertical shape, many users report significant relief from wrist pressure and pain after a week or two. This mouse is ideal for professionals and students seeking a more comfortable computing experience. All customs duties and GST are included in the listed price, with tracked delivery via ExpressBox.
Ergonomic Comfort for Extended Use
The ProtoArc EM11 NL vertical mouse is engineered to promote a healthier hand and wrist posture. Unlike standard mice that force a pronated grip, this design encourages a natural handshake position, significantly reducing the strain and discomfort associated with prolonged computer use. Users report improved comfort and productivity after adapting to the shape, making it a valuable tool for professionals and students alike. Imported directly from authorized US retailers, it offers authentic quality and performance.
Ideal for Small-Medium Hands, Not for All
This mouse is specifically designed for users with hand lengths under 7.5 inches (19.05 cm), offering a snug and comfortable fit. However, individuals with larger hands may find it less accommodating. While the silent clicks are great for quiet environments, the forward and back buttons are not compatible with Mac OS. For users seeking advanced programmability or a mouse for very large hands, alternative models might be more suitable.
