As others have mentioned, it has a problem with the battery, which moves and does not work after I fix it and it works. When I close the lid, the battery moves again and it's back to the same issue. In the meantime, I would like to point out that this is the second one I bought. The first one, as soon as I left the store and opened the package, the mouse was not properly attached from the factory and the back of the mouse opened up. I went and exchanged it immediately. This is the second one and unfortunately, it will also be thrown away

I have it for six months and it is very good for the intended use and comfortable in the hand, simple without extra buttons and functions, relatively lightweight with good connection to Windows and Android (personally, I would increase its price by 2.5 - 3 euros and add a Bluetooth receiver to it).

Do not buy it!!!
It was the only thing I found available in my area and in the midst of... lockdown.
I didn't even have a chance to use it because the battery didn't fit properly in its place, resulting in it never working!!!
If you still decide to buy it, keep in mind that you will need to spend even more money to buy a better mouse, so start from the beginning to avoid inconvenience!

Don't buy it! It doesn't work. Cheap, yes, but annoying too.
Let me explain: it fits well in the hand, normal noise, satisfactory range, battery life (included) I don't know, but you will be annoyed by its constant disconnecting from its position and therefore the deactivation of the mouse.
And I tried everything, papers, cardboard, etc. don't help much, as it seems to be a manufacturing problem.
I bought the cheapest equivalent Logitech I found on Skroutz and I was relieved...
