This is a wireless mouse that can connect to your PC via the included wireless USB receiver and with Bluetooth. The wireless USB receiver works on the 2.4 GHz frequency, and the Bluetooth connectivity supports LE (Low Energy) technology. The wireless coverage has a range of up to ten meters.

A view of the Logitech MX Master 3 mouse

The Logitech MX Master 3 is more than generous with its buttons. In total, it has seven buttons, including two wheels and a button that supports gestures.

One of the most impressive things about the Logitech MX Master 3 is its scroll wheel. Logitech says that it reinvented it, and says that the wheel can scroll an incredible number of 1000 lines per second.

That's made possible by the MagSpeed Electromagnetic technology used on the scroll wheel, and by its steel fabrication process. Furthermore, it is not only lightning-fast but also extremely quiet.

Logitech MX Master 3 gets its autonomy from a built-in rechargeable Li-Po battery with a capacity of 500 mAh. To charge it, you use the bundled USB Type-A to Type-C cable, and you can get three hours of use in one minute charging time.

Using the Logitech MX Master 3

Logitech MX Master 3 is a large mouse with a high profile. Unless you have small hands or if you are left-handed, its ergonomic shape and the thumb rest makes it comfortable to hold.

The buttons are also well placed. On top, you have the two left and right-click buttons, the scroll wheel, and a small button that you can press to manually switch the wheel's speed from high-speed to the precision mode and the other way around.

On the left side, you find the horizontal scroll wheel and two additional buttons beneath it. They are very easy to identify and press with your thumb, and they support macro actions so you can set them up to do whatever you want.

On the so-called wing of the mouse, there's another small button that you can miss if you're not looking carefully. This button is important because it allows you to perform gestures with your mouse. When you press it with your thumb, you can move the mouse in different directions on your desk to perform various actions.

Let's go back to the most showcased feature of the Logitech MX Master 3, which is its scroll wheel. The new electromagnetic technology used by Logitech makes it incredibly fast. It's enough to give it just a small push with your finger to make it spin at a speed that seems uncontrollable. That warp speed makes it ideal for those who work with long documents, spreadsheets, or similar files, as it allows you to scroll a huge number of lines per second, with just a bump on the wheel. However, the scroll wheel can also work in precision mode, which means that it can spin a lot slower when you need it to. The Logitech MX Master 3 automatically switches between these scrolling modes when you rotate the wheel slower with your finger, as well as when you press the small button beneath it, which we mentioned earlier in this review.

Another essential feature of the Logitech MX Master 3 is its sensor precision. It uses the company's Darkfield tech, and that means that it should work and be fairly accurate on all kinds of surfaces. We used it on a mousepad, on a desk, and even on a coffee table made of glass. We can testify that the Logitech MX Master 3 worked great on all these different surfaces, even on the glass table.

The optical sensor of the mouse has a maximum DPI value of 4000. That's more than enough for most users, but gamers might want more, so it would have been nice if the mouse came with a higher DPI sensor.

Regarding battery life, we can't say how long it is going to last you in the real world, as we would have to use this mouse for a couple of months to know that. However, we can say that it can charge in one minute enough to last you for a few hours. What's even better is that the USB Type-C charging port on it is placed on the front of the mouse, which means that you can continue using the mouse while it's charging. That's an excellent design choice.

We loved using the Logitech MX Master 3 mouse, and we believe that it's an excellent device for anyone. It's a well-rounded mouse that performs anything you ask from it admirably.

Logitech calls this feature Logitech Flow, and all you need to make it work is to install Logitech Options on all the computers on which you want to use it and make sure that they are all connected to the same network.
