Bottom Line: :Excellent ergonomic vertical mouse with killer multi-device connectivity and solid battery life.
Key Takeaways
- 👉 The vertical design immediately alleviates wrist strain, forcing a natural “handshake” posture, which is fantastic for long working sessions.
- 👉 Triple connectivity (Bluetooth 1, Bluetooth 2, and 2.4GHz dongle) means true multi-device freedom, making switching between a desktop and a laptop lightning fast.
- 👉 The rechargeable battery is a huge win, lasting several weeks on a single charge under normal use.
- 👉 While the plastic construction is comfortable, it’s certainly lighter than some premium competitors, which might feel slightly less substantial.

If you spend more than four hours a day tethered to a computer, you know that standard horizontal mouse grip is a ticking clock for wrist strain and potential RSI. I’ve personally battled carpal tunnel symptoms after years of video editing, and shifting to an ergonomic setup became less of a choice and more of a necessity.
That’s why I was genuinely excited to spend a month testing the ProtoArc EM11 NL. This isn’t just another vertical mouse; it promises the holy trinity of modern workspace essentials: comfort, rechargeable battery life, and true multi-device connectivity.
My biggest concern with multi-device mice is always the lag when switching machines. I routinely jump between my desktop PC and my MacBook Pro for work, and waiting even a second for the pairing to catch up drives me crazy. However, I was particularly impressed with how fast the three-device switching feature actually was—we’re talking milliseconds of response time, which I’ll detail in the connectivity section below. Stick around, because this might be the wireless freedom you’ve been waiting for.

Ergonomics and Design: The Handshake Grip
The first thing you notice about the EM11 NL is its shape. It looks like a spaceship landed sideways on your desk, but trust me, your wrist will thank you. The steep, 60-degree angle puts your hand into what’s often called the “natural handshake position.” This drastically reduces the forearm twist inherent in traditional mouse use.
When I first moved to a vertical mouse years ago, I felt a slight awkwardness for about an hour. It’s like learning to hold a pen differently. But with the ProtoArc, the transition was surprisingly quick. The matte black finish feels comfortable against the palm, and the thumb rest is perfectly molded. This mouse isn’t huge—it feels more mid-sized, which is ideal if you have average-sized hands like mine (I wear a size medium glove, for reference).
The button placement is intelligent. The two thumb buttons (Forward/Back) fall right where they should, and the DPI selector is easy to hit but stays out of the way during normal scrolling. Overall, this design is focused purely on mitigating strain, and after those long editing sessions, my wrist felt noticeably less fatigued than it used to.
Pro Tip: When setting up any vertical mouse, spend a moment adjusting your chair and keyboard height. Proper vertical mouse ergonomics require your forearm to be roughly parallel to the desk. If your desk is too high, you might introduce shoulder strain trying to compensate.
Connectivity and Multi-Device Magic
This is where the ProtoArc EM11 NL really earns its keep. It offers three distinct connections: Bluetooth 1 (BT1), Bluetooth 2 (BT2), and the 2.4GHz USB receiver. Switching between devices is managed by a small, labeled button on the bottom of the mouse.
I set BT1 to my work desktop (Windows 11), BT2 to my personal laptop (Mac OS), and used the dongle connection for my media center PC. The convenience is startling. I can literally finish drafting an email on my desktop, hit the switch button, and immediately start browsing Netflix on the media center, all with the same mouse.
The development of the vertical mouse can be traced back to the early 2000s, driven largely by medical professionals and ergonomists studying repetitive strain injuries (RSI) caused by the pronated forearm posture typical of traditional mouse use. The shift to a neutral wrist angle is considered the gold standard for long-term computer comfort.
The 2.4GHz connection is plug-and-play fast, of course, but the Bluetooth connections paired instantly and, crucially, maintained a rock-solid link. As promised, the actual switching process takes less than half a second. It’s truly effortless and speaks volumes about the quality of the internal connectivity chip.
Tracking Performance and Precision
A comfortable mouse is useless if it tracks poorly. Thankfully, the ProtoArc EM11 NL delivers crisp, precise movement suitable for general office work, browsing, and even light graphic design (though hardcore gamers might want something with an even higher polling rate).
You get three adjustable DPI settings (1000/1600/2400). I found 1600 DPI to be the sweet spot for a dual-monitor setup, offering the perfect blend of speed and control. The optical sensor works reliably on almost all surfaces I tested—wood, mousepad, even a slightly textured laminate desk—without skipping a beat.
The scroll wheel feels tactile and substantial, clicking with satisfying feedback as you navigate long documents or endless feeds. The main left/right click buttons are quiet. They aren’t silent, but they produce a soft, dampened click that makes them ideal for shared office spaces or late-night work sessions when you don’t want to wake the house.
Battery Life and Charging Experience
The fact that this mouse is rechargeable via an included cable (rather than requiring AA batteries) is a massive plus for me. I hate hunting for batteries, and it’s better for the environment, too.
ProtoArc claims excellent longevity, and in my testing, the claims held up. Using the mouse for eight hours a day, five days a week, I got nearly four weeks of use before needing a recharge. That kind of battery life means you can genuinely forget about the charging cable for a good while, making this a true wireless companion.
Recharging is simple—just plug it in. You can still use the mouse while it’s charging, which is a critical feature that far too many wireless peripherals miss.
Battery longevity in Bluetooth devices is heavily influenced by the version of Bluetooth used. Many modern peripherals utilize Bluetooth Low Energy (BLE), allowing devices like the ProtoArc mouse to maintain connectivity for weeks or even months on a single charge without the power drain of older wireless protocols.
If I have to nitpick, I do wish ProtoArc had included a USB-C charging port instead of the Micro-USB port it uses. Micro-USB is becoming outdated, and having to keep a separate, older cable specifically for this mouse is a minor annoyance in an otherwise streamlined setup.
How It Stacks Up
The vertical mouse market has grown significantly, but the ProtoArc EM11 NL manages to stand out, primarily due to its exceptional value and connectivity profile. Products like the Logitech MX Vertical offer a slightly more premium feel (heavier plastic, maybe better glide pads), but they often cost two to three times as much, and sometimes you have to pay extra for the tri-device capability.
The EM11 NL is positioned perfectly for the power user who needs comfort and device agility without the premium price tag. While it might not have the ultra-high DPI settings that specialized gaming mice offer, for productivity and general computing, it hits a spectacular balance of features and affordability. Its comfort level is easily on par with much more expensive ergonomic options.
