I got this because I wanted a quiet wireless mouse. It's lasted for several years by now and still is going strong. You can barely hear the clicks from the right and left mouse button. It has five different 'speed settings', but honestly I only use the last because the others are way too slow for me. I use the mouse for a few hours every day and the thing that's impressed me the most so far honestly, is how it's still working so well after I've dropped the stupid thing time and time again. It's like it wants to leap out of my hands when I have a bundle of stuff in my arms. But it still works!
