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

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.

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.

★★★★☆Really good ergonomic mouse overall, especially for long work hours. I used it for an entire workday right after getting it, and it felt comfortable the whole time. The movement is smooth and accurate, the clicks are quiet, and the texture feels nice and smooth in hand.I also like that it connects to my iPad through Bluetooth, which makes it convenient for switching between devices. My only complaint is that you have to lift the mouse to switch between connected devices. I wish there was a button on top instead, since some other mouse designs already do that better. Other than that, it’s been a great purchase so far.

It has a soft hand feel, smooth glide. It is easy to adapt to. It has a virtually silent click/ sound.Also helps with wrist relief. It is very light. It seems durable. It has good tracking.

This feels way too nice for $20 and worked instantly via the dongle, you can use it while charging, it's comfortable. The manual says stuff about learning curves, but it's honestly straight forward. I'm coming from a $200 gaming mouse and this thing feels worlds better (i no longer game, i have no idea how this thing is for gaming). it's quiet, comfy, has a nice weight, the scroll wheel is nice and feels nice to the touch, not sure if it's gonna break on me, but we'll see. I mean, it's $20 lol

A small ergonomic mouse, with an DPI button to adjust tracking sensitivity and USB-C charging. Includes a USB dongle as well as ability to pair with two bluetooth devices. The mouse buttons are the very welcome soft click variety that are very quiet and take very little force to depress. Scroll wheel has a little more than average resistance. Fwd and back button are on the left to help with web browsing. Tracking is good and there is lag. BT pairs easily with Windows.I wanted to like this mouse, but a couple of ergonomic issues prevented be from really getting comfortable with it. First, the "beaver tail" like base that extends under the hand is frustratingly boh too small and too large. It is too small such that it catches the bottom of my hand constantly as I use it, whereas if it were larger or smaller that would not be the case. It just happens to hit the sweet spot that it is a problem.The other bigger problem for me is the velvety soft slick coating they used on this making it very slippery in the hand. As a result I find myself having to hold on tighter than I would normally, which is bad ergonomically. I also suspect this coating over time this coating could degrade into that same sticky goo that similar devices with these coatings suffer from.

I have bought this twice, three times if you count the Jelly Comb mouse I bought before, because ProtoArc bought Jelly Comb). I bought the Jelly Comb mouse for work in 2020, and when I couldn't find Jelly Comb anymore in 2025, I bought the ProtoArc mouse, possibly for my home (?) in 2025.A few weeks ago, the scroll wheel of the Jelly Comb mouse wheel I had at work went wonky. (After six years). So I went to Amazon, found the mouse I'd bought last year that fit my hand perfectly and was basically exactly the same as my 2020 Jelly Comb mouse and helped with my carpal tunnel, and ordered another one.Predictably, it worked perfectly.But I like having a spare mouse around because sometimes they go bad, so I opened up the old Jelly Comb mouse (had to find a video about how to open an ergonomic mouse, but I figured it out), cleaned the wheel with rubbing alcohol, and put some PTFE tape between the wheel and the rubber, and it's working perfectly again.So now I have three perfectly working mice - one for home, one for work, and one for... trips, I guess? Or as a backup?The Jelly Comb mouse was perfectly fine and I would've ordered it again if I could've found it. It's a great mouse that basically lasts forever, and the batteries last so long I forgot the old one even *had* a battery in it, but then ProtoArc went, "You know what? Making our customers buy batteries is silly; we should just include the batteries *and a USB C charging cable*; that'll be a nice extra touch," though they did that, too.Oh, and they also apparently thought, "Sure, we have a USB adapter *and* bluetooth, but what if people want to connect it to, like, two devices but they want to use Bluetooth for both? What if they have, idk, a desktop, a laptop, and a phone, and they want to use bluetooth to connect to their laptop and phone and can plug the USB dongle into their computer? Better throw in the ability to easily pair with TWO devices via bluetooth!"But that's not what inspired me to write this review. It's the packaging. ProtoArc clearly pays their designers very well. The box looks like something Apple would design. When I opened the box I kinda rolled my eyes and thought, "This is a cheap mouse that does not need packaging this pretty."I'm writing this review in 2026. By the time I need another mouse, I can't imagine how they'll have thought how to make this thing better because it was exactly what I wanted in a mouse before. They'll probably have figured out a way to make sure the mouse wheel doesn't get sticky and need taken apart and cleaned after 6 years. (GASP! Maybe they already did... I'll find out in like 6 years 😂They did a great job. If I lost enough mice that I needed another one, or if enough of them broke that I needed to buy another, I would buy another one from them.I've also thought about buying one of their ergonomic keyboards, that's how much I like their mice.NOTE: ProtoArc did not pay me to say any of this, or offer me anything in exchange for writing this review, and this is not AI. I just really like this mouse.

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

I dont have wrist pain after ling shifts at the desk. Glides smoothly and easy on the wrist. Highly recommend.

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)

ماوس جميلة وانيقة ومريحة وسلسة
