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. ### ⭐⭐⭐⭐⭐ Great mouse for 1st vertical *by on Reviewed in the United States July 30, 2026* 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. ### ⭐⭐⭐⭐⭐ The product is basically perfect; I didn't need the packaging to be so pretty... but it was. *by on Reviewed in the United States July 25, 2026* 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. ## Frequently Bought Together - ProtoArc Ergonomic Vertical Mouse, EM11 NL Rechargeable Wireless Mouse Bluetooth, Ergo Mice with 3 Multi-Device for PC/Notebook/Laptop, 2.4GHz Optical Mice for Windows, Mac OS, Gray - ProtoArc Backlit Bluetooth Ergonomic Keyboard, EK01 Plus Full Size Wireless Split Keyboard with Dual Bluetooth and USB, Cushioned Wrist Rest, Rechargeable, Compatible with Windows/Mac/Android, Grey --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/659959767-em11-nl-wireless-ergonomic-vertical-mouse-rechargeable-gray-58-vertical](https://www.desertcart.co.th/products/659959767-em11-nl-wireless-ergonomic-vertical-mouse-rechargeable-gray-58-vertical) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-08-15*
