I can't say which one deserves more of the credit since I started using them together, but WOW. Within a day, I noticed a huge difference in how my arm and wrist felt while working. This mouse is incredibly comfortable. The vertical design puts my hand and wrist in a much more natural position than my traditional mouse. The instructions say to allow one to two weeks to adjust to using a vertical mouse, but honestly, I was comfortable with it on the first day. My hands are about average size, and the mouse fits my hand perfectly. I also love that it can connect to three devices. I currently have mine connected to two different laptops, and pairing was almost instantaneous. There was really nothing to it. I was a little concerned about using Bluetooth because one of my laptops has a tendency to lose its connection with other Bluetooth devices, but I haven't had any connection issues with this mouse. The battery life has been impressive too. I've been using it for about a month, have only charged it once - when it first arrived, and it's still going. It's your typical black mouse, but it feels durable and well made. My one annoyance is the scroll wheel. I sometimes inadvertently press down on it while scrolling, which activates auto scroll. The auto scroll isn't particularly smooth either, so I'd rather not activate it at all. I'm getting better about not accidentally pressing the wheel, but it still happens occasionally. Paired with my ergonomic mouse pad, this has made working at my computer so much more comfortable. The comfort alone made the switch worthwhile for me, and the battery life, easy pairing, and ability to use it with multiple computers are bonuses I actually use. Review: Not perfect, but as close as one can expect - I bought a mouse because I was starting to get occasional pain in my first knuckle. I watched a LOT of reviews on YT and bought the expensive Logitech MX, but the buttons 4 and 5 were in a terrible spot. So out of desperation I bought another four vertical mice that were cheap, totally 80, which is what I paid for the MX. I liked one of the TECKNET mice with the volume knob, but my favorite is this EM11: * Silent, effortless clicking. * Excellent button placement. * Best vertical mouse angle. * Battery lasts a long time. * And the thing is beautiful. * No software, but doesn't need it, which is nice. * Bluetooth performance is perfect. My only "complaint" is that when I press and hold button 1, it can unclick itself. I actually sent one of these mice back because I thought it was a defect. The second mouse did it, too, but it just had to press the button more firmly on drag. That sounds like a pain, but it's second nature, now, and doesn't happen anymore--or only very rarely. If you're thinking of getting an MX--just don't. This is far better and a quarter of the price. I highly recommend it. ## Features - Perfect Fit for Small to Medium Hands: Designed specifically for hand lengths under 7.5 inches (19.05 cm), the EM11 NL reduces wrist strain by aligning with your natural grip. Please measure the size before ordering for a better fit and more comfort - Connect up to 3 Devices: This ergonomic wireless mouse features dual Bluetooth connectivity and 2.4G USB-A connectivity modes for simultaneous connection of up to 3 different devices, and is compatible with Windows 8, Windows 10 or higher, Mac OS X 10.12 or higher, and Android 4.3 or higher - Rechargeable Ergonomic Mouse: The Bluetooth Vertical Mouse has a built-in 500mAh Li-Ion battery that can be conveniently recharged using the included Type-C cable(The Type-C cable is for charging only) - Ergonomic Vertical Design: The ergonomic mouse wireless keeps your wrist naturally straight, putting your forearm and wrist in a more natural and relaxed position, which can reduce discomfort and strain, helping to improve productivity and reduce the risk of repetitive strain injuries compared to a standard mouse. Warm tips: We encourage you to relax your palm and hold the mouse naturally when using a vertical mouse - Learning curve: Since it takes a learning curve to get used to the shape when using our ergonomic mouse for the first time, it may cause inconvenience to your mouse grip, We recommend that you take 1-2 weeks to get used to it, as many users find that it will help reduce the pressure and pain on your wrist caused by long-term use of the mouse and improve comfort - Adjustable Dpi & High Performance: 1000/1600/2400 DPI levels provide higher sensitivity than standard optical mice for precise optical tracking; with the back and forward buttons, you can easily navigate websites and increase work efficiency. Note: All buttons are not programmable and the forward and back buttons are not compatible with Mac OS systems - Quiet Clicking: The silent click sound of the left and right mouse buttons help you focus on your work, Note:the middle scroll wheel and and the back/forward buttons are not silent - Connection Guide: This mouse pairs via Bluetooth or the included USB-A receiver only.

The battery life between charges is great. The usb-c charging port is in a good location so it's easy to use while charging, the ergonomics are good even for my larger hands, using it just feels natural. The ability to switch from the USB dongle and 2 other devices over bluetooth is seamless with the push of a button. Paired devices recognize the switch immediately. DPI is good and the optic handles different surfaces well. Overall good build quality and has survived many hours in a dusty work environment. If you're considering this mouse just buy it now. ## Frequently Bought Together - ProtoArc Ergonomic Mouse, EM11 NL Bluetooth Rechargeable Wireless Vertical Mouse, 3 Multi-Device Connectivity for Computer/PC/Laptop, 2.4GHz Optical Mice for Windows, Mac OS, Black - 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, Blue --- ## 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.no/products/623608259-em11-nl-wireless-ergonomic-vertical-mouse-rechargeable-black](https://www.desertcart.no/products/623608259-em11-nl-wireless-ergonomic-vertical-mouse-rechargeable-black) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-28*
