Review on Silent Portable Wireless Shhhmouse i440: USB Receiver, Multi-Surface Operations, 3 DPI Levels - for Laptops, Computer, Mac, PC [Black & Red] by Robert Castro

Really very calm. Love it! Fits well. my hand is small The backup buttons are on the side, I press too often, but I think that's the default position. You can easily adjust the mouse speed. I uploaded a short video to show the audio differences. It's dramatic. The only thing I noticed is that the doctors say he falls asleep after 13 minutes. I think it's a typo as mine probably sleeps through 3! and that's okay. I recommend this mouse. It even came with a battery!
