Review: Love it ! - One month review: I've been using this device for several hours each day since 19 January 2025, connected to a Chromebook via the USB wireless dongle. It's tremendous! Set up was instant - just plug and play. The Chromebook found the device and offered a range of customisation in Settings/ Device. I've configured the top two small buttons to be magnifier on/off and audio on/off. The mouse is easy to use, with smooth and responsive cursor and scroll movement. It's comfortable on hand and wrist. The only improvement I'd want is for the scroll-wheel to have a knurled texture, rather than slippy-smooth, but I'm getting used to it. Through the customisation options I've changed the track-ball and cursor movements to suit my preference for speed and precision. Very happy with this product.
Review: Great trackball - The best and smooth trackball mouse.

### ⭐⭐⭐⭐⭐ Great trackball
*by A***R on 26 December 2025*

The best and smooth trackball mouse.

### ⭐⭐⭐⭐ Nice mouse, needs a little wearing in
*by M***E on 16 October 2023*

Having a small collection of mice and a couple of ball mice like this, I thought I would give this a try for something I can take out with me when I am working. The mouse is quite compact, with the receiver going inside the mouse, this is useful if you are like me and end up losing the dongle in my bag. The unit came with a battery which is stated to last 18 months. Quite useful as it will likely last a lifetime in my bag as it won't always be getting use. The ball itself is a beautiful shade of blue, its a glossy well polished finish. The ball can be easily popped out using the button on the underside for cleaning. My only gripe with this, much like other ball mice like this is that the contact points for the mice aren't that well polished. You will need a few weeks of use to smooth these out from use. The ball is no means scratchy, but from time to time, you will get a sticky point or a crunchy turn that means you aren't quite as precise. I have an Elecom Huge and I ended up swapping these out for glass ones which smoothed out the feel quite dramatically. I can recommend doing the same with this, if you don't want to go through a break in process. The body of the mouse is a black plastic, its quite smooth and I did find my hand slipping off of it. However the texture is nice and the plastic doesn't feel cheap, it feels quite premium and a nice surface to touch! The whole mouse is at a slight angle and means that your wrists sits in a far more natural angle. This means that you can navigate for much longer amounts of time and would be good for people with wrist aches or some sort of RSI. The buttons on the mouse are nice and tactile, a great amount of sound feedback and clickiness to tell you it has been pressed. The scroll wheel on this is really what lets it down. It has a very very smooth surface, so much so, it can feel like you are scrolling the wheel without actually doing so. I found this quite frustrating and would of preferred it was knurled or bumpy so that I could tell if it was turning or not. When you do turn it, there is an audible click to it. The mouse overall though is a really well made one. It feels premium and over time, I can see myself enjoying this mouse more and more. 4/5!
