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: Excellent comfortable and smooth mouse - I am rarely moved to review an item, but this mouse is such an improvement on my previous (Microsoft) wireless mouse that I just had to write one. The first nice surprise was that the mouse is rechargeable via a little USB-C port underneath the grip. Having been used to supplying endless batteries for my previous mouse I was really pleased about this. It was really easy to connect the mouse to Windows (using my previous mouse!) via the Bluetooth options in Windows 11, and once connected, it stays connected reliably. This is another bonus as I don't have to use a USB port for the optional included USB receiver, which is slotted into the base of the mouse. I can keep this option handy in case I need to use the mouse elsewhere or on a device without Bluetooth. The mouse itself is incredibly easy to use and comfortable to hold. The curve is perfectly matched to the open grip of my hand, and the buttons are perfectly placed for clicks. The surface material is very smooth yet slightly rubberised so you don't lose contact while using it. Talking of clicks, the mouse buttons are responsive and the clicks are precise yet also soft, so there is less noise than my previous mouse. The mouse is very smooth to move across my desk, and due to this it feels almost weightless, like an extension to my arm. The scroll wheel is responsive, with subtle 'stops' as you turn it, but provides smooth movement through documents or for zooming. The DPI setting, which I haven't adjsted yet as I haven't felt the need, makes the pointer move fluently on the screen, and for this reason I feel I am working more efficiently and smoothly than I was before with my old mouse. Overall I would say this item is exceptional value for money, really well-designed, and I would recommend it highly for anyone needing a new mouse for either productivity or gaming.

### ⭐⭐⭐⭐⭐ Comfy, silent ergonomic mouse that you need for your office :)
*by S***T on 22 March 2026*

Today I got the ProtoArc EM11 (I PURCHASED, didn't get this item free) and honestly.. SO comfortable. Seen a few reviews complaining and this made me worry.. however, after trying this mouse I can't agree with a single bad complaint so far. Perfect mouse size, great value for money, works on my mac well (size buttons work) and the mouse DOESN"T move away from you when you go to grab it lol, saw one review showing that but they were just throwing their hand at the mouse. Honestly so far... amazing value for money. My issue with ergonomic mice is that then moving over to the keyboard I know them over lol, but with the shape of this one I haven't had that issue at all. The mouse is silent clicks (deep sounding) clicky side buttons but that is to be expected on any mouse. Super comfortable hand fit in the ergonomic position. I see that this company actually sell a hand rest too? I can see how that would make this feel EVEN better! So would be very interested in that. Overall, really good mouse and would recommend you buy.
