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, Wine Red

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.

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 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.

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 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.

The ProtoArc EM11 NL is a fantastic ergonomic mouse. The vertical design feels natural and has significantly improved comfort during long hours of work. The Bluetooth connectivity is reliable, the rechargeable battery lasts a long time, and switching between multiple devices is seamless. Smooth, responsive, and comfortable—this mouse has exceeded my expectations. Highly recommended!

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.

Okay
