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

I use the ProtoArc EM11 NL Vertical Mouse every day at the office, and it’s made a noticeable difference in wrist comfort. The vertical design keeps my hand in a more natural position, which really helps during long hours on spreadsheets and emails. Bluetooth setup was quick, tracking is smooth, and the clicks are quiet—great for a shared workspace. Battery life has been solid so far, and I love that it’s rechargeable. Great value and a big upgrade from a standard mouse. Highly recommend for office use!

After using it for several days, I can confidently say this is one of the best upgrades I’ve made to my workspace. The ergonomic design truly makes a difference—my hand rests in a much more natural position, and I’ve noticed significantly less strain in my wrist and forearm. The buttons are responsive, the scrolling is smooth, and the grip remains comfortable even during long work sessions. The build quality feels solid and well-designed. It’s ideal for anyone who spends long hours at a computer or wants to prevent issues like wrist pain or carpal tunnel syndrome. Great value for the price. I would definitely buy it again.

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.

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.

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.

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.

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.

يبغى له شوي عشان تتعود لكن، ما شاء الله تبارك اصلي و جودته مرة حلوة والتغليف احترافي مرة ومن لما شريته ما عبيته ومر اسبوعين تقريبا ما شاء الله تبارك الله اللهم بارك

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 mouse is great. It feels nice position your wrist in a nice comfortable position. I liked it so much that I bought one for My Wife! Good quality build came with a nice charge cord. I only charged it once I’ve had it now for a good two months without having to recharge.
