It's also the first mouse in the lineup using Logitech's newly developed BOLT receiver, designed to provide improved wireless security and performance in congested signal environments. The changes with the newest version include quieter buttons and higher sensitivity levels, which is helpful for 4k displays with much higher pixel densities requiring increased sensitivity levels to produce cursor movements at a comfortable speed. They also have two separate scroll wheels, one on the side for horizontal scrolling and another on top that handles vertical scrolling. They all pair wirelessly with up to three devices via Bluetooth or USB receiver and have an impressive advertised battery life of up to 70 days. Each mouse in this series has a comfortable, right-handed shape with a thumb rest with an integrated button for gesture commands. The differences between versions are minor, and older generations frequently go on sale. The best Logitech mouse for work and everyday browsing we've tested is the Logitech MX Master 3S however, all models in the MX Master lineup are great choices.
