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: Premium feel with excellent versatility - What can I say about this mouse? It feels like pure premium quality. The ergonomics are perfect for various hand sizes, and it's very easy to keep clean. It glides beautifully across surfaces, and the Bluetooth connectivity is surprisingly seamless. I mostly use the wireless dongle connection, so having both options included is a huge plus. The unboxing experience was great—it comes with the charger and even a note from the designer. If I could change one thing, I’d move the thumb buttons just a few millimeters higher. I might just be used to different ergonomic mice, so my muscle memory is looking for them elsewhere, but it’s likely just a matter of getting used to the new layout. Overall, I love it. ## 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.

Overall, I love it. ### ⭐⭐⭐⭐ Perfectly good mouse *by L***A on 7 December 2025* This is generally a great mouse, has really supported me to continue to use a computer and is easy to use, smooth tracking and is a great fit for my hand (medium female hand size!). I've had no issues with Bluetooth or wired mode and great value for money. It seems well made and does what I need it to. The only slight issue is it takes time for your fingers to remember where the left and right buttons are and I still often find it difficult to use without looking at the buttons but this will improve with time. ## Frequently Bought Together - ProtoArc EM11 NL Ergonomic Mouse, Wireless Vertical Mouse Rechargeable Optical Mice with Multi-Device (Bluetooth + Bluetooth + USB Connection), 3 Adjustable DPI for Computer, iPad, Mac, Windows, Green - ProtoArc Backlit Wireless Ergonomic Keyboard, EK01 Plus Ergo Keyboard with Wrist Rest, Split Design, USB-C Charging, Bluetooth and USB, Natural Typing Compatible with Windows/Mac/Android --- ## 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.pl/products/657531308-em11-nl-ergonomic-mouse-wireless-vertical-mouse-rechargeable-optical-mice](https://www.desertcart.pl/products/657531308-em11-nl-ergonomic-mouse-wireless-vertical-mouse-rechargeable-optical-mice) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-28*
