I bought the mouse in early December. She is very good in the hand. The key arrangement I like very much. The freewheel I need not really often, but now and then is also very helpful. Large prints are available for the mouse wheel. At the tender age of 3 months, the middle mouse button was no longer right and for some time they refused to work most of the time completely. In addition, the mouse wheel with or without freewheel starts his own business and uncontrolled scroll down in documents. So there can be absolutely no longer work, they have just thrown in the trash. Previously had a M505, which has always worked almost 4 years in continuous use.
