Sounds like you are talking about old mechanical mouse because you have mentioned scroller wheel.

Believe it or not, this kind of mechanical mouse is not too difficult to fix if it is just that the wheel is not smooth enough.

I remember in the past I did fix many old mechanical mouses simply by removing dusts accumulated inside it.

Well, It's an optical mouse with a wheel for scrolling at the top. It doesn't have a ball at the bottom which I think the biggest thing about a mechanical mouse. I haven't used such a mouse in 10-12 years. The problem with this one is this scroll wheel doesn't work anymore. But the mouse works fine. After that, I bought a cheap Cordless mouse which worked great for years. It's after that one broke I started having problems with every mouse I have bought.

You are lucky, indeed. Since my very first cordless mouse, I have yet to find one which works fine. I have bought 4-5 units so far and i could have bought an expensive one from all that money I wasted on those.
