Had before this mouse the MX 518 non refresh was very happy with this and I have after this intense after 3.5 years of use abgegrifen a little and has become anansehnlich ordered the Refrech. And I can only say it is as good as the old with the improvements leicheten sizes sliding feet are very good. Otherwise everything is fine, the key comes with a good and defined pressure point. Whether for play, work with Office or surf the Web, this mouse is suitable for all.
