I've been using the mouse for a week or two now and I'm so happy I got it, the quiet clicks of the mouse is so much nicer than hearing constant loud clicks like most other mice, it still feels very responsive when clicked however. The two buttons on the side can be customised by using logitech options software, which is a really nice touch! The size of the mouse is also really nice, and it's got rubbery grips on the side so it's very nice to use. It comes with a Logitech unifyng receiver inside the mouse if you don't like using bluetooth, and the battery is meant to last for quite a while. I got this on sale and I would really recommend it!
