I'm looking to buy a new mouse that doesn't have mouse scrolling problems after a couple of months. I've had 3 mouses and all of them stopped working properly after 6 months or so. I'm looking to buy one that will last me at least 2 years, I don't care if it costs me more money as long as its a normal mouse (none of those weird shaped ones) and it lasts for a long time without any scrolling problems or any other problems. Also I have cleaned them but the problems keep coming back. Therefore does anyone what brand mouse and model type I should buy?
