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!

### ⭐⭐⭐⭐ 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.
