Amazon currently has the Logitech MX Master 2S available for just $79. That's good for $20 off of its regular price, and also brings this back down to its all-time low.
The Logitech MX Master 2S debuted last year, as Logitech's newest productivity mouse. It is a fairly large mouse, but it is also a really comfortable mouse to use. And it connects to your device using Bluetooth. The MX Master 2S can actually connect to three devices simultaneously, which means you can connect it to multiple computers or smartphones and tablets. Logitech also makes it easy to move files between these machines with your mouse, which is pretty impressive when you think about it. Logitech says you'll get around 70 days of battery life out of the MX Master 2S, and it recharges using a micro USB port. So there's no need to worry about keeping batteries around for this mouse.
