ProtoArc Mice & Keyboard EM11 NL Vertical Mouse Mouse with Side Scroll EM25 Fast Scrolling Mouse Mouse Mat Wrist Support Mechanical Keyboard Mouse KM60 Keyboard Mouse EK01 PLUS Ergo Keyboard Review: Good mouse that has helped reduce my elbow pain - Very pleased with this mouse. I bought it because I have recently been suffering with tennis elbow and it was suggested that using one of these might reduce the pressure on the tendon which causes the pain and the joint itself. It took a bit of getting used to, coming from a normal mouse, but I soon got used to it and find it extremely comfortable to use- your hand/arm is in a more natural and relaxed position, putting less stress on the elbow, as it is no longer twisting so much. In terms of setting up, the tiny usb bluetooth dongle set itself up in Windows 11 straight away and connected to the mouse with no problem and I've had no issues with disconnects or connections from the bluetooth connection. The mouse feels solid and well made and is of a soft feel/matt texture, so very comfortable to use and feels as though it will be durable over time. It seems accurate, I've had no lag or skipping of the cursor during any normal use. I've not tried gaming with it yet. For me, it's been worth the money - I'd seen these before and wondered if they were a gimmick, but since I've been using it (combined with an erganomic keyboard from Arteck), I can now see that it isn't and it has reduced the pressure on my elbow/tendon which has in turn reduced the pain. It might not be for everyone, but it's a thumbs up from me. Review: Shockingly good quality. Easily rivals my MX Master! - I bought the ProtoArc EM11 NL on a whim looking for a solid ergonomic option, and I am absolutely blown away by the value here. "Amazing" doesn't even cut it. My daily driver is a high-end Logitech MX mouse, so my standards for ergonomics, build quality, and comfort are pretty high. I fully expected this to feel like a "budget backup," but it feels incredible in the hand. The contouring is spot-on, the grip is comfortable for long working hours, and the tracking is incredibly smooth. If you are on the fence because of the price point, don't be. To get this level of premium feel and comfort at a fraction of the cost of a mainstream flagship mouse is a total steal. Highly recommended! ## Features - 【Ergonomic Design and Enhanced Comfort】The wireless ergonomic mouse features an extended wrist rest that hugs the palm of your hand and promotes a more natural and relaxed position for your forearm and wrist. This design helps minimize the risk of injury from repeated strain and reduce muscle tension in your arms to ensure comfort throughout the day - 【Connect up to 3 Devices】This ergonomic wireless mouse offers both BT 5.0 and 2.4G USB dual connection modes, allowing it to connect to three different devices simultaneously. Switching between devices is as easy as clicking the mode switch button. Compatible with Windows 8, Windows 10, Mac OS X 10.12 or higher and Android 4.3 or higher (No RGB lighting!!!) - 【Rechargeable Battery】The vertical mouse is equipped with a built-in 500mAh Li-ion battery, which can be charged via the supplied Type-C cable(For charging purposes only). After 30-minute inactivity, the mouse automatically switches to sleep mode to save energy and can be woken up by simply moving. Besides, the low battery indicator reminds you to charge the wireless mouse when the red light flashes - 【Adjustable DPI and Practical Features】Our bluetooth ergo mouse features convenient forward/backward buttons for easy web browsing. The 1000/1600/2400 DPI levels offer higher sensitivity than conventional optical mice and enable precise optical tracking. In addition, the whisper-quiet click of the mouse helps you to focus on the essentials. !!!NOTE: All buttons are not programmable and the forward and back buttons are not compatible with Mac OS systems - 【Warm Note】ProtoArc EM11 NL vertical bluetooth mouse is recommended for medium small hands(Palm size: <17.5CM and 17.5CM-19CM, about the length of 3 bank cards), mouse size 13.8*6.9*6.8cm (5.43*2.72*2.68in). To get a more comfortable fit and a better user experience, we recommend measuring the size of your hand before buying - 【Note】We understand that some customers may feel uncomfortable when first using our ergonomic mouse. It is important to note that transitioning to an ergonomic design may take 1-2 week getting used to. It may require getting familiar with a new grip and positioning. We encourage you to give yourself some time to adjust, as many users find that once they acclimate, the comfort and support significantly improves their overall experience.

Highly recommended! ### ⭐⭐⭐⭐ The mouse wheel cannot spin freely! *by S***N on 11 June 2026* Good: -- Much higher quality than its price would suggest. -- Very light, even with a built-in battery. -- Seamless Bluetooth connection. Bad: -- The wheel cannot spin freely! If you are used to the Logitech way of giving the wheel a spin to get back to the top or bottom of a page, then this click-click-click only wheel will irritate you. -- For smaller hands. I actually get some wrist cramp from using this because my fingers are a bit squished together on the buttons and wheel. ## Frequently Bought Together - ProtoArc EM11 NL Ergonomic Mouse, Wireless Vertical Mini Mouse Rechargeable Optical Mice with Multi-Device (2*Bluetooth + USB Connection), 3 Adjustable DPI for Computer, iPad, Mac, Windows Black - Arteck Split Ergonomic Keyboard with Cushioned Wrist and Palm Rest, 2.4G USB Wireless Comfortable Natural Ergonomic Split Keyboard, for Windows Computer Desktop Laptop - EooCoo Mouse Pad Wrist Support with Massage Design, Ergonomic Mouse Mat,Wrist Rest Pain Relief Mousepad with Memory Foam & Non-Slip Silicone Base (12x8 inch,Black) --- ## 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.pt/products/635235200-em11-nl-wireless-ergonomic-vertical-mouse-rechargeable-black-multi-device](https://www.desertcart.pt/products/635235200-em11-nl-wireless-ergonomic-vertical-mouse-rechargeable-black-multi-device) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-07-10*
