It’s been still about a couple months and still can’t fathom how perfect for my need. I don’t have to move my hand around only the thumb and barely any strain after full day of work. Very underrated product. ### ⭐⭐⭐⭐⭐ Excellent purchase *by on Reviewed in India 26 December 2025* Best mouse I've had so far, used to own a Logitech ergo m575 which was good for short bursts of usage but for longer workdays I felt pain in my palm and the joints of my fingers, did a bit of research and decided to try a mouse with a more neutral handshake position and it's the best decision I've ever made, pain is gone! Also high quality build, smooth scrolling, great feel, all around quality product ### ⭐⭐⭐⭐ Best Mouse *by on Reviewed in India 15 July 2026* Nice ## Frequently Bought Together - ProtoArc Vertical Wireless Trackball, EM05 NL Bluetooth Ergonomic Rollerball, Rechargeable Computer Laptop Thumb Mouse, 3 Device Connection, Compatible with iPad, Mac, Windows, PC - Gray - ProtoArc Wireless Trackball Mouse, EM01 NL Ergonomic Bluetooth Rollerball Thumb Rechargeable Computer Laptop Mouse, Adjustable Angle & 3 Device Connection for PC, Mac, Windows-Gray Ball - ProtoArc Wireless Ergonomic Keyboard, EK04 2.4GHz Wireless Ergo Keyboard with Separate Numeric Keypad, Split Design, Wrist Rest, Rechargeable, for Desktop, PC, Laptop --- ## 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.uk/products/776819556-protoarc-vertical-wireless-trackball-mouse-em05-nl-bluetooth-ergonomic-rollerball](https://www.desertcart.co.uk/products/776819556-protoarc-vertical-wireless-trackball-mouse-em05-nl-bluetooth-ergonomic-rollerball) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-10-14*
