As the advertisement states, the product is operating well. The rolling ball operates smoothly and is very ergonomically designed, not putting pressure on the wrist. It is very comfortable to use.

I’ve wanted a trackball mouse for a long time! I always hear that this kind of mouse is the first choice for gaming and 3D modeling. I used to have a mouse like this. At that time, computers were still very bulky. Later, this kind of mouse gradually fell out of popularity. I really miss the smoothness and controllability of this trackball mouse. I have also read some claims that it is more beneficial for the wrist. No matter what kind of computer you use, this might be one of the best accessories you can buy.

It has a smooth texture and an extremely stunning effect. I like it very much.

Great! I lost my Logitech mouse and need a replacement. This one is very similar, but it is lighter and thinner than Logitech’s. I really like its Bluetooth connection function. There’s no need to plug in a cable. I was a little worried originally because my computer only had a Type-C interface. I would give it 10 points, or even 20 points!

It works very well from the very beginning and is as excellent as similar products with higher prices. It seems that this is a very cost-effective choice. This trackball is wireless, has a built-in battery and can be charged via USB.
