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.

### ⭐⭐⭐⭐ The mouse wheel cannot spin freely!
*by S***N on 11 June 2026*

Good: -- Much higher quality than its price would suggest. -- Very light, even with a built-in battery. -- Seamless Bluetooth connection. Bad: -- The wheel cannot spin freely! If you are used to the Logitech way of giving the wheel a spin to get back to the top or bottom of a page, then this click-click-click only wheel will irritate you. -- For smaller hands. I actually get some wrist cramp from using this because my fingers are a bit squished together on the buttons and wheel.
