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

What an awesome buy for me! I’ve been in the technology field for over 20 years and was a technology enthusiast for many years before. Using a standard mouse had been detrimental to both of my hands. I have been using external track pads for several years now. I discovered this mouse at a great price and decided to take it for a spin. I can’t stress how comfortable it is to use and the functionality and control over my mouse pointer is fantastic! Amazing to include three device connections switch too! What a great value. It’s rechargeable and feels like a quality product in my hand. Highly recommend but do check if you have very large hands this may not be for you. I would recommend this mouse to family and friends to prevent issues with their hands and have a more comfortable computing experience. I did pick up a mouse pad for better pointer control. My wood desk was not great with the optical lasers and the pad fixed that issue.

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.

This is such a great mouse! I have been struggling with wrist pain for a while from using a mouse all day for work. I was recommended to get a vertical mouse by my doctor. He said they keep your wrist in a more natural position. I spent a while looking for one that I like, and I basically narrowed it down to either this or the Keychron M5. The only other ones that seemed appealing were the 2 Logitech models, but they were both far too expensive. I have also heard horror stories about their durability. Finally, I saw this model on sale for $19, so I pulled the trigger. I am very happy I did. Even after just a few days my wrist pain improved. The grip feels very natural. The way they describe it like a handshake is very accurate. I am happy that I don't have to deal with so much pain in my wrist anymore after a long day sitting at my PC. I think the multiple connection methods are nice too. I can keep the USB dongle plugged into my desktop workstation and switch to the Bluetooth whenever I need to use it with my laptop. I don't use it with my laptop that often, but I do have a Thunderbolt dock at my desk that I use occasionally. Switching input methods works well. I have not noticed any input latency or lagging. Nor have I had connection drop-outs. There are no drivers or software to install. That is greatly appreciated because I can't stand having peripherals that need to install special drivers and applications to configure the settings. This has none of that crap. You just connect it and you are good to go. I'm a Linux user as well, and I've had no issues. The DPI switch is nice to be able to change the sensitivity. I was worried the silent buttons would feel mushy, but they don't at all. Somehow they have a very tactile click without making any noise. The noise isn't an issue for me, but I can imagine anyone working around a bunch of other people would appreciate it. The scroll wheel feels really nice too. It has a nice soft-touch finish and smooth operation. The forward and back buttons feel nice, but they are not silent like the left and right click. It's not that big of a deal, but it would have been a nice touch. For those who are gamers, I don't think this would make a great gaming mouse. For that I will probably hang on to my ultra lightweight mouse that has a honeycomb shell for ventilation and weight reduction. This mouse is by no means the heaviest mouse I have used, but it is nowhere near as light as my gaming mouse. I cannot speak on the battery life since I have not had it that long, but I will say after a week I have not had to charge it. at all. I just pulled it out of the box and started using it. Perhaps if I have an issue with the battery life I will update this review in the future. You really cannot go wrong with this ergonomic mouse.

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).

The ProtoArc EM11 vertical ergonomic mouse has been a fantastic upgrade for my workspace. I spend long hours at the computer, and this mouse has made a noticeable difference in reducing wrist strain. The vertical design feels natural from the moment you start using it, and within a day or two, it becomes second nature. The Bluetooth connection is reliable and quick with no lag, and I love that I can switch between devices effortlessly. The mouse glides smoothly, tracks accurately, and feels incredibly responsive whether I’m working, browsing, or doing basic editing. Battery life has been excellent as well. A single charge lasts much longer than I expected, and the rechargeable feature makes it even more convenient. The overall build quality feels solid, and the matte finish gives it a premium feel. If you’re looking to ease wrist discomfort or simply want a more ergonomic setup, this mouse is absolutely worth it. It’s comfortable, efficient, and a noticeable improvement over a standard mouse. Highly recommended!

When I tell you that this is a game changer...immediately you feel how much more comfortable it is from the original mouse. Your hand sits in a more natural position. It feels really durable. Connectivity was super easy - hard press on the button on the bottom until it flashes, pull up the bluetooth devices on your laptop/desktop, choose the ProtoArc...DONE. I chose the black one but it looks like they've got all kinds of different colors. Functionally it works great...no latency and it moves really smooth on my mouse pad. I'm a professional photographer and hours of photo editing are going to feel just that much better now without my hand getting sore. I definitely love the look of it as well. I would highly recommend to anyone especially for those that do lots with the mouse.

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.

This is the second vertical mouse I've owned. It replaces my previous model whose left click button was getting overactive for some reason. Anyway, I like the hand feel of my previous mouse just a little better, but they are very similar, and this one is growing on me. The only slight niggle I can find is that the ProtoArc feels like the grip is slightly slicker but it hasn't affected functionality in any way. Buttons are responsive and well-placed and mechanical function is good also. It is silent and does what it is supposed to do with no fuss or muss. It's easy to charge but I can't tell you how long it lasts at this point. This ergonomic mouse fits my medium sized hand well. I think it would be hard to beat at the current price point. ~ Kort
