Bought this two months ago & use it almost everyday with a win 10 laptop. Initial charge has lasted about 2 months. The included usb charging cord makes it easy to recharge and the mouse is usable while it's plugged in. You can turn it off with the bottom switch or leave it on; it will go to sleep if not being used and only requires a mouse click to wake back up. Technically, the mouse clicks are not completely silent - more like a very soft, muffled sound. But in a room with normal sounds (TV, talking, gaming, etc...) you more feel the clicks with your finger than hear with you ear. Using the default 1600 dpi has worked for fine for me. This mouse is not tall in an ergonomic way, but being slimmer makes it more compact and easier to stow in the laptop bag. Its a good mouse for the price.
