Apple’s Mighty Mouse is a terrible product. It’s is a good mouse for about 2 months of heavy use. After that, that little ball stops working properly and after that is only downhill. It has a good resolution, but the little ball just destroys everything. I have had 4 Mighty Mouses at home, 2 of them were cordless, and all of them ended up with the exactly same issue. Overuse malfunctioning of the little annoying ball. They don’t last 2 months. Thank god Apple created the magic mouse. I bought one, and it is great. I still do some odd scrolling with it, but it’s ok. It’s a good mouse.
The best mouse I have ever had is an old logitech mouse, from 10+ years ago. I bought it to replace the even worse mouse from my first iMac ( a Graphitti iMac DV ) when I was 14 year old. That rounded mouse were terrible. So I bought this logitech, and it still works great. I still carry it, in case my magic mouse fails me. I have this problem, I don’t fully trust cordless mouses.
