After using in twenty years all kinds of mouse models, I am very happy with it very simple that works perfectly and is inexpensive. Just plug the antenna into a USB socket and presto! it's over. The mouse works immediately with no software to install, no DVD. It has two buttons and a knob, but also has the great advantage of being almost silent, which is significant in certain circumstances (work at night for example). So, I gave up a Microsoft mouse much more sophisticated that eventually annoy me because of its noise too loud clatter. The AmazonBasics model has a button to turn it off and make piles of money. Manufacturers should think more about this question of noise and simplicity, common sense.
