EM11 NL Wireless Ergonomic Vertical Mouse, White | 58° vertical design supports a natural wrist posture; connect 3 devices via Bluetooth/2.4G USB-A; 500mAh USB-C rechargeable.

I bought a mouse because I was starting to get occasional pain in my first knuckle. I watched a LOT of reviews on YT and bought the expensive Logitech MX, but the buttons 4 and 5 were in a terrible spot. So out of desperation I bought another four vertical mice that were cheap, totally 80, which is what I paid for the MX. I liked one of the TECKNET mice with the volume knob, but my favorite is this EM11: * Silent, effortless clicking. * Excellent button placement. * Best vertical mouse angle. * Battery lasts a long time. * And the thing is beautiful. * No software, but doesn't need it, which is nice. * Bluetooth performance is perfect. My only "complaint" is that when I press and hold button 1, it can unclick itself. I actually sent one of these mice back because I thought it was a defect. The second mouse did it, too, but it just had to press the button more firmly on drag. That sounds like a pain, but it's second nature, now, and doesn't happen anymore--or only very rarely. If you're thinking of getting an MX--just don't. This is far better and a quarter of the price. I highly recommend it.

I absolutely love this mouse. The ergonomic design is incredibly comfortable and keeps my hand and wrist in a much more natural position, especially when I’m working at my computer for hours at a time. The buttons are easy to reach, it feels smooth and responsive, and the shape is comfortable without being bulky. It also looks sleek on my desk and feels much more premium than I expected. If you spend a lot of time on a computer and want something comfortable, functional, and easy to use, I highly recommend it. Definitely a 5-star purchase!

I have been very surprised by this mouse! I bought the ProtoArc in a pinch when the click buttons on my Logitech ergo mouse started malfunctioning, also thinking it could be a back up / travel mouse. Honestly, I’ve come to prefer the ProtoArc over the Logitech. The ProtoArc is a little wider, as such it fits my natural grip very well, I’ve had no issues utilizing it for hours at a time. I can’t use a “standard” mouse for more than 10 min before my hand starts cramping up. Tracking has been spot on, all the buttons and wheels have held up fine after several moths of use. The buttons have a nice feel, so I know when it has clicked, but without an obnoxiously loud click noise. The ProtoArc has also held up to the occasional fall off the desk 🙈 At 1st I didn’t think I’d ever use the dedicated USB wireless radio, but I’ve come to enjoy it, makes it very easy to connect with some of the locked down devices I use. Additionally I’ve been able to connect the Bluetooth with both my MAC and PC computers without issue. While the Logitech has more buttons and some software to configure the buttons, I can’t say I ever used them after setting it up, nor do I miss them. After the initial full charge on the mouse, I have yet to recharge it, that is with utilizing it Monday-Friday 8+ hours a day for work, and here and there after work and weekends. I was initially thinking it’d get maybe a week at a time, similar to other value mice, but I’m overly impressed that it’s conserving power so well! The only thing I wish it had was the ability to freewheel the scroll wheel, I can’t fault it, I think it’s been over a decade since I’ve seen a mouse with that option. Give the price of the ProtoArc vs the Logitech, I’ll be buying several more of the ProtoArc.

Have been using it for 3 months. Mouse is comfortable if you're looking for vertical. The rubber coating is good, and hasn't worn down noticeably from three months use for video editing, writing, and coding. Primary mouse buttons are silent switches, which feel better than expected for the price. The scroll wheel I'll get back to at the bottom of this review because it's my primary complaint. The forward/back buttons are in the right spot and feel good to use. Battery life is very good (comparable to rechargeable logitech mice, which is a huge win). USB-C charging is also a very welcome addition at this price. I'm gonna talk about gaming performance now, since I have the means to test it. I know most people won't care about this so feel free to skip. Latency is low enough to use with competitive FPS games. It's not as fast as a dedicated gaming mouse, but I genuinely struggled to notice a difference at 240hz compared to my logitech and razer gaming mice. DPI only goes up to 2400, which is perfectly usable, but I personally run 3200 at low sens on all my other mice, so I personally wish it went up a little higher, but it's not an issue if you only use one mouse. The PTFE skates at the bottom of the mouse aren't fast enough for gaming, and the positioning of them can cause a little drag if you're aggressively moving the mouse, but this isn't an issue at all for this mouse since I'm just noting it for completion purposes. The big issue for me was the scroll wheel. It works well if you're scrolling slowly, but as soon as you try to scroll quickly down a page, it starts to "miss" and starts to scroll at about half the speed. Not sure if it's a polling rate issue or something, because I've been able to reproduce it consistently, and I've cleaned out the mouse with compressed air plenty. Regardless, it's something I noticed when I tried to scroll quickly down long documents or webpages. In normal reading usage it doesn't matter, but whenever I tried to get quickly down a page I would notice it. It's enough of a problem where I'll personally go look for another mouse, but I do think this mouse is an excellent introduction into vertical ergo mice for its price.

I've been using this mouse for a bit now and am genuinely impressed with the quality, especially given the low price point. It feels well-constructed, operates smoothly, and offers great comfort during long hours at the desk. The vertical angle takes a short adjustment period if you're coming from a traditional flat mouse, but it makes a noticeable difference in reducing wrist strain. Excellent value for money—highly recommended if you're looking for an affordable ergonomic upgrade.

This mouse if perfect. This mouse fells right for man hands. The ergonomics regarding how it feels in the hand is great. Although, I would like to know the process of how the ergonomics was thought of because, the only issue I find is where the pinky rest. Your have your index finger and middle finger resting perfectly in the mouse left and right clicks. Even the scroll wheel while is not that rapid in speed one could have hope for, it is fine and is easy to use as well with your middle finger. What I love about this mouse is how the DPI sits right there in between my two fingers, because I don't even need to lift the index or the middle finger to change the speed of the mouse. I can actually with the middle portion of my middle finger, change the speed by clicking the DPI button. It is funny if they thought of it like that to be used. Because it does work for me like that fine. It has a nice tracking because of that option with the DPI It's durability it seems to be tied with the material, which it does feel incredible by being plastic it helps the hand move it with out issue. This mouse feels like it is the perfect ergonomic system to hold your hand rather than the other way around. I am glad I try these types of mouses that have this type of ergonomic convenience. Nigel and his team did a great thing with this one. I truly recommend this mouse.

Good mouse, and works fine. This was my first vertical mouse, and I picked this one for 2 reasons: Good reviews independant of Amazon, and I could connect up to 3 seperate devices. I combined this mouse with a protoarc wireless keyboard, and it has really de-cluttered my desk. Setup is easy, and it comes with good instructions. I haven't had any issues with pairing via bluetooth either. Be aware that the buttons cannot be re-progamed on the NL version, only the pro version allows that. My hands are not big enough (according to their sizing chart) to use the pro, so I'm stuck with the default settings. Unfortunately I've accidentally hit the forerward, or back buttons and lost work. This is not good when I am editing photos.

I purchased this mouse as an investment for my work, and I'm very happy with it. I have arthritis in my hands, so using a traditional mouse for long periods can be uncomfortable. The ergonomic design lets me rest my hand naturally, and I can move the mouse using my whole hand instead of putting strain on my fingers and wrist. The side buttons are also much easier to reach. I'm left-handed and accidentally ordered the right-handed version, but it still works well for me. They do offer a left-handed model, which I'll likely purchase in the future. Another thing I appreciate is the rechargeable battery. It lasts a long time on a single charge, and since it comes with a charging cable, there's no need to keep buying batteries. If you spend hours at the computer or have hand or wrist discomfort, I definitely recommend giving this mouse a try.

Great but not for large hands. Learn to place your fingers at non-natural positions to use. Maybe best for smaller people.

This ProtoArc ergonomic vertical mouse is such a good buy. It has two connectivity modes (USB-A and Bluetooth) which work great out of the box with no need for any software installations. With the Bluetooth connection, you can connect up to two devices. While you cannot use them simultaneously, you can easily switch between them with the click of a button. Other features include: 1. Power: It is powered through USB-C, and you will find yourself recharging only about every three to six months depending on your use. It charges quickly. 2. Navigation: It has two side buttons for moving forward or back on a webpage, although there is no built-in native app to edit these buttons. Overall, it is great for your hand and recommended for people with big hands.

Okay

The product designer is a complete genius. The mouse is very practical and convenient, with great features.

Heads up. If you're a graphic designer wondering if this is what you think it is, it IS. It functions exactly the same but it's marketed for ergonomics so it's way cheaper.. My lines are buttery smooth using this. Sure, I rocked without it, but this feels like cheating. ❤️ (been using it for awhile now still on the first charge, connecting via the wireless USB it comes with)
