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

Work gave me free rein to buy a mouse. I could’ve gone with much more expensive options. I asked for this one. I’m a digital artist and repeat motion injuries are a huge concern. The shape holds your hand up in a way that’s much more natural. I cannot go back to normal mouse controls. This is just so much more comfortable. The mouse is responsive and durable and feels high-quality. The charge seems to last a good while. I’d just plug it in every once in awhile when you’re not going to use the computer. The matching protoarc mousepad adds to this to make things just so much less painful than they were. I’m 5’5”, I have smaller hands. If you have big meaty claws because you are a Large Man of Great Heights you might want a bigger mouse. If you are an Average Size Man if Normal Height it might be alright. I am a Woman of Average Height and this is the perfect mouse grip size for me. Keep that in mind when ordering - there’s much bigger types of this sort of mouse out there if you know you have big hands.

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.

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.

Ergonomics 5/5: Feels great, instant relief from arm and shoulder pain. Felt a little strange at first but got used to it within a hour. Build quality 4/5: Plastic feels great just wish it had a little more grip to it. Quiet clicks Worked on my linux distro out the box. Really affordable option. Things I wish for: Larger size. My hand with their measurement would be considered medium but still feels on the edge of being too small. I wish there was a larger resting area for thumb, pinky, and the back of the mouse. I just get this feeling that it might slip out of my hand even though it doesn't.

Great mouse, does not hurt the hand when using it for lengthy periods of time. I got the basic color , but if you want to be fancy shmancy, get a different color that resonates with you. Personally I wanted the burgundy one, but I just figured I would get black to match the aesthetic of my desk. Functionality is great, you can connect to three devices; one with a 2.4Ghz dongle, and 2 devices wirelessly vis a vis bluetooth. I use the dongle on my Mac through...surprisingly, another dongle. And the 2 wireless options are occupied by my windows machine and linux machine. (I am a multi OS user since I have many use cases). Battery life is great, I've only charged it about 2 times since I got it, so battery life is quite long for the price you'd get it at. Durability is great, though I do notice that it attracts a lot of the sebum (skin oil) so it's wise to clean it a few times here and there to keep it in good shape and to preserve the color you got it in.

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.

Okay, let me start by saying that I have used Logitech Marble pointing devices, or something similar almost exclusively for the last 20 years, And I love them ! But LogiTech Marbles are getting scarce (and expensive) and I have had varying success with pretenders, so I thought I would give this a try. And while I have gotten used to it, I still DON'T like it. And I know that alot of that has to do with my prejudices & use case, so keep that in mind. First of all, I am not sure if this is a sensitivity issue, a communications one, or just the battery - but it is very jumpy. I used to have my old, corded pointer at a level BELOW my computer cuz that's where I had space. And it worked fine. But for some reason this CANNOT get a clear signal from there. So I rearranged things so it's on an even level now. It's better, but still iffy. So I tried charging it again. It improved, but started getting jumpy again. So I LEFT it plugged in (keep in mind it does not work corded, so I still have to use the dongle) and same problem. And I tried using both BT channels as well and it's no better. On top of all this. now my desktop is too crowded. Like I said, I usded a Masrble for 20 years and my desk was setup accordingly. I didn't NEED space for a traditional mouse. So I am relegating this as a spare pointer, and getting another Marble copycat. It just does not work for my day to day use ! NEW UPDATE: I wanted to be sure I shared something regarding this review. The Vendor (Proto Arc) reached out to me directly & offered me a full refund. They did not HAVE to do so, but I appreciate the offer ... even though I did NOT accept it. I do like Proto Arc products & I still use their version of the LogiTech marble in my work office. And while my situation did not make using this vertical mouse viable, it would probably be fine elsewhere. And as I said previously, I will keep this in my bag for when I needd a spare/emergency pointer. Still, it was very nice of them to offer me a refund. Thank You for that ! FINAL Update: Just thought I would tack this on in regards to my experience with this. My main complaint was that I was not getting a consistent wireless signal. And that was why I am NOT using this with my home PC. Now, it just so happens that I ordered a pair of Wireless Earbuds for my youngest, but she was not happy with how they fit her ears. So I decided I would try them out. I paired them with my Home PC .... and I had the same issue with the earbuds that I had with the Vertical Mouse. They failed to maintain a consistent connection via BlueTooth. So the issue is not with the Mouse OR the Earbuds ... it's with MY PC. and it's placement. So I will reiterate ... this is a good vertical mouse & a great value. It just doesn't work in my situation.

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.

Iv owned pretty much every ergonomic mouse under the sun. This is fantastic. Very comfortable. I have big hands and it fits well. Really nicely made and the materials are premium. Buttons are great and it's Bluetooth all for $50 AUD. Can't get much better.
