Expensive but worth its weight in gold. I have an extremely miserable job which involves opening and closing hundreds of browser tabs to amend one small item each time. Previously this could take hours but the same task now is done in minutes thanks to the perfect setup of the side scroll and the familiar infinite main scroll. The new mag wheel is a true delight to use and the mouse is very well built. The added ability to fully customise the 'thumb' rest button is also perfect, i'm sure there will be further uses I'll find for Indesign and Illustrator in future. Finally something better than my previous favourite the MX1100 and have now retired my MX Performance and Apple Magic Mice of which do not compare to the practicality and convenience this MX 3 offers.
