ProtoArc Ergonomic Mouse, EM11 NL Bluetooth Rechargeable Wireless Vertical Mouse, 3 Multi-Device Connectivity for Computer/PC/Laptop, 2.4GHz USB-A Optical Mice for Windows, Mac OS, Black

TLDR: Absolutely go for it!!!!! You'll be missing out on a lot if you don't get this!! Okay fellas, buckle up as I am about to yap about how incredible and awesome this mouse is. I've been a lifelong windows PC enthusiast, and on a budget. Therefore, that meant I used a lot of mice, but budget friendly mice. However, last year I finally jumped ships to a MacBook Air and the trackpad in there blew my mind. It was just fantastic. However, I also edit a lot of stuff, and that meant a lot of clicking and dragging and with the trackpad I had to compromise on the efficiency a lot. So, I decided to get a new mouse. An ergonomic mouse. I wanted to go with a Logitech ergonomic mouse but that was way too expensive and I just know that we're paying more for the name brand and not necessarily the product. So, I continued my search and that brought me to this gem of a product. It was very affordable and cheap. The quality and feel is just fantastic. The material feels so solid and comfortable. The scroll wheel is awesome. You can adjust the DPI, you can connect multiple devices to this mouse. The color looks perfect. Gosh there are keys that you can customize to. (Now, I know you can do that with a lot of other regular mice too, calm down). But hey, the best part of the mouse, your hand posture feels so so so good. There's tiny details that enhance the user experience. There's a tiny extension of a curve where your palm rests which is not really noticeable until you feel it. It took me two days to get used to it. But in just less than a week I'd say I became a pro, and now in two weeks I crave this. For the car enthusiasts this feels so good just like driving as you hold and shift the gear-shifter. Ufff. So good.

This is the most comfortable mouse I have ever used. It beats everything I have tried from Logitech - MX Master, MX Ergo, Trackball. If they added a side scroll wheel, it would be the perfect mouse.I am truly shocked at how comfortable it is to use. I have pretty bad carpal tunnel syndrome, and this mouse is a gamechanger for me. It glides smoothly on the desk. The buttons are plastic but have a quality feel. The support it offers at the base (it runs a bit under the back of your hand) is a unique touch. It has a soft-touch rubbery feel which feels great, but I do worry that it won't wear well, as I have had peripherals with similar surfaces get stained or, worse, become sticky to the touch. Right now, it feels nice. The scroll wheel is smooth. Setup was pretty easy - I used BT. The BT connection has been very stable and quick. It works great with my Win 11 laptop.

I think I’ve had this mouse for at least a year at this point and can’t say I’ve ever experienced an issue. Connectivity is great and response. Quickly can switch between multiples PCs and the ergonomics of it are great compared to a standard mouse. I think it’s helped greatly with past wrist pain. The battery life is great. I try to remember to charge it maybe over night once a month if that. It’s never died on me. All in all a solid mouse at a great price compared to other similar mice.

I bought this mouse as I need an ergonomic mouse for my home laptop, that meet a couple of criteria: - Bluetooth capable ( I don't like dongles) - Relatively inexpensive (I was aiming for sub $50) - Comfortable for large hands ( I am over 6' tall) This mouse does well at all 3 of these. The bluetooth works well it is responsive and the mouse has no issue working on Windows 11 or Linux Ubuntu. Expense wise this is one of the cheaper options, this is why I was willing to risk the purchase even though I am unfamiliar with ProtoArc as a brand. Size wise at best I would call this a "medium" sized mouse. I have a Logitech vertical ergonomic mouse at work that is very well sized, and I was hoping this one was similar. unfortunately it is not. At this time this is not a deal breaker as, at home, I am not on my computer for hours at a time, unlike at work. Due to the low cost of the item I can forgive it not fitting my hand , but I am casually looking for a replacement. So would I buy this know what I know now: probably not. I would try something else as I would rather have a larger mouse and other than the cost savings there is nothing that stands out. I still gave it four stars as the product is good, it just doesn't fit me, and that is not the products fault. Note: it would be nice if amazon had a built in reviewer that showed real life size that was independent of the manufacturer presentation for products like these (keyboards, mice headphones, headphones, etc).

I have Med-Large hands which I think is important to remember when you read this review. Hand size is very important when you're considering vertical mice. For me, I switched to vertical mice due to carpal tunnel a couple years ago, and it really helped to eliminate it. I went to Best Buy and tried both the Logitech Lift and MX Vertical. The Lift is for smaller hands and I didn't like the feel of it. So I bought the larger MX Vertical despite the $100 pricetag with the hope that it'd help my carpal tunnel. It did, but unfortunately, now its suffering from the double click issue that apparently is a feature of Logitech mice. So I began the hunt for another vertical mouse that didn't cost +$100. I knew I wanted one that was for Medium to Large hands, so I tried 3 different ones that said they were for larger hands or had similar measurements to the MX Vertical. None of them I ended up keeping for various reasons. So I bought another one hoping for better luck. Pros: This mouse feels great in the hand with a nicely textured surface. It also has some of the most satisfying buttons of any mouse I've tried with a very tactile yet soft, quiet click. The scroll wheel is nice much like the MX Vertical. The shape was exactly as described and felt like a hand shake. Despite the smaller size, I really enjoyed holding this mouse and my wrist did not drag on the mouse pad. Finally it has a rechargeable battery (which can be a con for some) and was under $20. It also comes in different colors. Cons: The con is that my hands are too big. They recommend this mouse for S-M hands vs the M-L of the others I tried, and I definitely agree. My little finger drags horribly if i put my hand in the "correct" placement. I got around this by putting my 1st finger on the left side of the first button and my 2nd finger on the right, and then use my 3rd finger as the right click, which gave my pinky room on the mouse. It worked okay but wasn't ideal. I really wish ProtoArc made a super sized version of this mouse. (Side note: I saw a knock off version of this mouse with the exact same measurements that said it was for M-L hands. Thank you ProtoArc for an accurate description) Ultimately I ended up returning it due to my hand size, but I really wish either my hands were smaller or the mouse was larger so that I could have kept it. Please ProtoArc, make a larger version for those of us with larger hands. If you did that, I'd buy it immediately.

This ProtoArc EM11 NL is one of those “low cost, high impact” upgrades—especially if you’re grinding long hours at a desk. It’s not flashy, but it quietly fixes one of the biggest problems in modern work: wrist fatigue. The vertical design is the star here. It puts your hand in a more natural handshake position, which genuinely reduces strain compared to a traditional flat mouse. The built-in wrist rest helps support your palm, making it easier to stay comfortable during long sessions.  Connectivity is another win. You can bounce between multiple devices (Bluetooth + USB) without constantly re-pairing, which is clutch if you’re running a laptop + desktop + tablet setup.  It just makes your workflow smoother. Performance is solid for everyday use. Adjustable DPI (1000/1600/2400) gives you enough control for productivity, browsing, and even light design work.  It’s not a precision gaming mouse—but that’s not what it’s built for. Battery life holds up well, and being rechargeable means no constant battery swaps—small thing, big quality-of-life upgrade. Now, keeping it real: • It’s a budget mouse, so the buttons feel a bit basic • Takes a few days to get used to if you’ve never used vertical mice • Might feel large if you’ve got smaller hands  But once you adjust, it’s hard to go back. Bottom line: If you want a cheap, effective way to improve ergonomics and reduce wrist strain, this is a no-brainer. It’s not luxury—but it’s practical, comfortable, and gets the job done without overcomplicating your setup.

The mouse is comfortable, the wrist position and angle are fine and it seems to be well made, however, there is a big issue for people with big hands and fingers on the thicker side: the button area is extremely narrow. If you compare this to a regular "flat" mouse you'll quickly notice that each button is about half an inch in width whereas a normal mouse has close to an inch for each button. If I put my 3 middle fingers together, they exceed the width that ProtoArc designed for the buttons + the scroll wheel. This is a major issue because no learning curve will help you adapt and this mouse is advertised for "large hands" which is not true.

I bought this because: My wrist hurt My old mouse felt like a torture device I was one click away from filing a workplace injury claim (at home) What I got: Comfort ✔️ Less pain ✔️ A mouse that looks weird but works miracles ✔️ This mouse has a vertical “handshake” design with a built-in wrist rest, which keeps your wrist in a more natural position and reduces strain compared to standard flat mice Translation: 👉 Your wrist finally gets a break First few days: Feels weird Your brain is confused You question your life choices Then suddenly: 👉 “Wait… my wrist doesn’t hurt anymore??” Now I: Use it all day without pain Can actually work longer without discomfort Look at regular mice like they betrayed me Also: Rechargeable battery = no constant battery swapping Bluetooth + USB connections = works with multiple devices Adjustable DPI settings = smooth and responsive Things I love: Huge relief from wrist strain Comfortable for long hours Quiet clicks (no aggressive office noise) Things to know: There’s a learning curve (give it a few days) Looks like a futuristic potato You will never go back to a normal mouse Unexpected side effects: Judging people still using flat mice Feeling like you upgraded your entire setup Saying “ergonomics matter” like a professional Final verdict: If you’ve got wrist pain from a standard mouse… this thing is a game changer—your wrist will thank you immediately.

Excelente mouse, probé varias marcas y modelos, pero este es el. Único ergonomico qué tiene un excelente agarre y rinde bien en videojuegos. Tiene buen sensor se nota.

This thing is really award winning good. And very cheap pricewise. I couldnt find a single ergonomic mouse with this quality and price. Pros: usb c charging , connectivity with 3 devices and very good material feel on the hands and great holding angle for the palm. Longevity will be seen over time

De gran calidad

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
