I could’ve gone with much more expensive options. I asked for this one.I’m a digital artist and repeat motion injuries are a huge concern. The shape holds your hand up in a way that’s much more natural. I cannot go back to normal mouse controls. This is just so much more comfortable.The mouse is responsive and durable and feels high-quality. The charge seems to last a good while. I’d just plug it in every once in awhile when you’re not going to use the computer.The matching protoarc mousepad adds to this to make things just so much less painful than they were.I’m 5’5”, I have smaller hands. If you have big meaty claws because you are a Large Man of Great Heights you might want a bigger mouse. If you are an Average Size Man if Normal Height it might be alright. I am a Woman of Average Height and this is the perfect mouse grip size for me. Keep that in mind when ordering - there’s much bigger types of this sort of mouse out there if you know you have big hands. ### ⭐⭐⭐⭐⭐ Great device for the price! *by on Reviewed in the United States May 7, 2026* I think I’ve had this mouse for at least a year at this point and can’t say I’ve ever experienced an issue. Connectivity is great and response. Quickly can switch between multiples PCs and the ergonomics of it are great compared to a standard mouse. I think it’s helped greatly with past wrist pain. The battery life is great. I try to remember to charge it maybe over night once a month if that. It’s never died on me. All in all a solid mouse at a great price compared to other similar mice. ### ⭐⭐⭐⭐⭐ Great mouse for everyday use. *by on Reviewed in the United States February 3, 2026* Great mouse, does not hurt the hand when using it for lengthy periods of time.I got the basic color , but if you want to be fancy shmancy, get a different color that resonates with you. Personally I wanted the burgundy one, but I just figured I would get black to match the aesthetic of my desk.Functionality is great, you can connect to three devices; one with a 2.4Ghz dongle, and 2 devices wirelessly vis a vis bluetooth. I use the dongle on my Mac through...surprisingly, another dongle. And the 2 wireless options are occupied by my windows machine and linux machine. (I am a multi OS user since I have many use cases).Battery life is great, I've only charged it about 2 times since I got it, so battery life is quite long for the price you'd get it at.Durability is great, though I do notice that it attracts a lot of the sebum (skin oil) so it's wise to clean it a few times here and there to keep it in good shape and to preserve the color you got it in. ## 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.com.sa/products/623608259-ergonomic-mouse-em11-nl-bluetooth-rechargeable-wireless-vertical-mouse-3](https://www.desertcart.com.sa/products/623608259-ergonomic-mouse-em11-nl-bluetooth-rechargeable-wireless-vertical-mouse-3) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-06-04*
