Hand size is very important when you're considering vertical mice. For me, I switched to vertical mice due to carpal tunnel a couple years ago, and it really helped to eliminate it. I went to Best Buy and tried both the Logitech Lift and MX Vertical. The Lift is for smaller hands and I didn't like the feel of it. So I bought the larger MX Vertical despite the $100 pricetag with the hope that it'd help my carpal tunnel. It did, but unfortunately, now its suffering from the double click issue that apparently is a feature of Logitech mice. So I began the hunt for another vertical mouse that didn't cost +$100. I knew I wanted one that was for Medium to Large hands, so I tried 3 different ones that said they were for larger hands or had similar measurements to the MX Vertical. None of them I ended up keeping for various reasons. So I bought another one hoping for better luck. Pros: This mouse feels great in the hand with a nicely textured surface. It also has some of the most satisfying buttons of any mouse I've tried with a very tactile yet soft, quiet click. The scroll wheel is nice much like the MX Vertical. The shape was exactly as described and felt like a hand shake. Despite the smaller size, I really enjoyed holding this mouse and my wrist did not drag on the mouse pad. Finally it has a rechargeable battery (which can be a con for some) and was under $20. It also comes in different colors. Cons: The con is that my hands are too big. They recommend this mouse for S-M hands vs the M-L of the others I tried, and I definitely agree. My little finger drags horribly if i put my hand in the "correct" placement. I got around this by putting my 1st finger on the left side of the first button and my 2nd finger on the right, and then use my 3rd finger as the right click, which gave my pinky room on the mouse. It worked okay but wasn't ideal. I really wish ProtoArc made a super sized version of this mouse. (Side note: I saw a knock off version of this mouse with the exact same measurements that said it was for M-L hands. Thank you ProtoArc for an accurate description) Ultimately I ended up returning it due to my hand size, but I really wish either my hands were smaller or the mouse was larger so that I could have kept it. Please ProtoArc, make a larger version for those of us with larger hands. If you did that, I'd buy it immediately. Review: Great mouse for 1st vertical - 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. ## Features - Connection Guide: This mouse pairs via Bluetooth or the included USB-A receiver only. Note: A USB-C receiver is not included.

It has a virtually silent click/ sound. Also helps with wrist relief. It is very light. It seems durable. It has good tracking. ### ⭐⭐⭐⭐⭐ The Most Comfortable Mouse I Have Ever Used *by J***D on June 5, 2026* This is the most comfortable mouse I have ever used. It beats everything I have tried from Logitech - MX Master, MX Ergo, Trackball. If they added a side scroll wheel, it would be the perfect mouse.I am truly shocked at how comfortable it is to use. I have pretty bad carpal tunnel syndrome, and this mouse is a gamechanger for me. It glides smoothly on the desk. The buttons are plastic but have a quality feel. The support it offers at the base (it runs a bit under the back of your hand) is a unique touch. It has a soft-touch rubbery feel which feels great, but I do worry that it won't wear well, as I have had peripherals with similar surfaces get stained or, worse, become sticky to the touch. Right now, it feels nice. The scroll wheel is smooth. Setup was pretty easy - I used BT. The BT connection has been very stable and quick. It works great with my Win 11 laptop. ## 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.tw/products/659959767-em11-nl-wireless-ergonomic-vertical-mouse-rechargeable-gray-58-vertical](https://www.desertcart.tw/products/659959767-em11-nl-wireless-ergonomic-vertical-mouse-rechargeable-gray-58-vertical) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-08-06*
