It's a mouse.
Works great with no problems.
It is a good mouse.
For the price, this is a very nice optical mouse.
I prefer plug in mouses for my laptop computer work and this one does the job.
In the last couple of weeks it's started to show problems.
For example, I have to try multiple times to highlight (to copy/paste) text, because the mouse skips around and loses focus, even when I have a firm grip on the buttons.
The wheel doesn't have precision, it is quite stressful.Outside of that, it works well for the price.
Most of my mice last for many years.
And of course the warranty expired not long before the the issue was bad enough to notice.
