The MX Master 4 is Logitech’s latest wireless mouse in the MX series, featuring a new haptics-equipped thumb grip that can provide tactile feedback while multitasking. It just launched last week at $119.99, but Best Buy has it available in multiple color schemes for $89.99. You don’t need me to tell you that this is a fantastic deal, given that it’s an improvement on the already-great (and, as of now, slightly pricier) MX Master 3S that came out in 2022.
The haptics implemented in the MX Master 4 may not unlock a new paradigm of productivity for you (clicking in the haptics-equipped thumb rest opens up the Actions Ring, which has been available for some time on past products), but it’s nice to have. One haptics setting that I particularly like allows the haptics to buzz when your pointer floats from one monitor to the next, which is handy for keeping track of its location.
Other improvements include the USB-C Bolt transmitter in the box, with which other Logitech devices can link through. Its design is mostly unchanged, but its plastic feels like it’ll last longer than the soft-touch shell on the MX Master 3S.
