Reviewing The MX Master 3

Logitech stayed true to its tradition of customization and ergonomic design by using premium materials and major software upgrades for MX Master 3. Designed for creatives and engineered for coders, it is simply like no other conventional mouse—even when compared to MX Master and MX Master 2S, earlier units from the master series.

Parts

 MX Master 3 has a large thumb rest and 8 functional buttons:

Gesture button (1) acts like a function key on a keyboard and is intended to be used for managing media, panning, zoom, rotation, and accessing custom tasks.

MagSpeed wheel (1) is for vertical scrolling (top to bottom or bottom to top) which performs line-by-line scrolling and free-spinning scrolling.

Thumb wheel (1) is for horizontal scrolling (right to left or left to right) usually in a spreadsheet or in a coding environment.

Mode shift button (1) is intended for you to be able to manually change scrolling modes.

Back and forward buttons (2) generally enhance navigation and simplify tasks specifically in dealing with document pages and in navigating web pages.

Click panels (2) are a typical mouse’s common functions known as “left click” and “right click”.

Design

 MX Master 3 has a high-end feel all thanks to its latex grip material and its hefty design. Logitech made just small refinements but with premium upgrades on its design, specifically if you were to compare it with earlier units from the master series. These include: 

• The left and right click panels are a bit more squared off as opposed to circular-edged click panels of the earlier versions.
• The extended contours of the thumb rest looks a lot less awkward as it seems to be a part of the mouse now. 
• The MagSpeed wheel (scrolling wheel) is made of stainless steel updated with electromagnetic technology, something you will not find in other mice and brands. 
• The back and forward buttons are larger than before and it’s easier to tell which is which with just your thumb because of the evident gap between them.
• The gesture button is now marked with a small, raised line which makes it easily recognizable.

MX Master 3 Battery Capacity

 MX Master 3 stays powered for up to 70 days on a full charge, which takes just 2 hours. From a minute of quick charging, you can use it for up to 3 hours. Its battery is a rechargeable Li-Po with 500 mAh. To charge it, you can simply plug into your PC and use it as a wired mouse because the charging port is strategically located in its front part. Its charger is also an upgrade to USB-C cable from the former micro-USB cable.

Multiple Device Pairing

The mouse perfectly works well with Windows, Mac, and Linux operating systems. It can be paired with up to three devices simultaneously. To do so, connect one device using an included 2.4GHz unifying adapter and connect the other two devices wirelessly over Bluetooth. You can easily switch between your connected devices to share files, text, and images all at the same time using the gesture button. You can also set your preferred settings depending on which app or program you’re using. 

 With the unifying adapter, you can also connect multiple Logitech devices that support unifying connections which means if you pair the MX mouse with an MX keyboard, you will be able to use them both while filling just one USB port.

Scroll Wheels

The stainless steel scrolling wheel, the most visible and evident upgrade, can be up to 90% faster and about 87% precise compared to other mice and brands. There are two modes to the scroll wheel: ratchet mode and free-spin mode. A ratchet mode lets you precisely scroll up and down through a web page or a document while a free-spin mode lets the wheel scroll as fast as it can on its own through magnetic force. This means that magnets in the center of the wheel add resistance at certain points, simulating a feeling of graduated ticking as you scroll line by line.

 You can scroll while using both modes. You can also manually switch from one mode to another by pressing the mode shift button just below the wheel. Logitech claims that the wheel can scroll a whopping 1,000 lines in 1 second with free-spin mode while being silent!

 Scroll conveniently anytime and anywhere as the mouse still uses Logitech’s Darkfield high precision sensor which tracks at up to 4,000 dots per inch (dpi). This basically means that you can scroll on any surface such as wood, glass, and aluminum.

Best Use Cases

 MX Master 3 is a palm-grip mouse intended for right-handed people, which could be a bit frustrating for lefties. People with small hands might have trouble getting a nice hold of it too as the mouse is rather large. Generally, though, it can be comfortably used for several hours because of its thumb rest and soft-edged shape.

 Although it seems as if it is designed to be used in an office or to be used for work-related matters, the mouse can also be used even for non-competitive or casual gaming. It’s a professional-looking mouse that is perfect for everyday use.

 For around a hundred dollars, inclusive of 1 USB-C charging cable and 1 USB receiver, you’re ultimately paying for the ability to control multiple devices and make per-app customizations as much as you can. With such powerful features and functions, you can consider MX Master 3 a premium mouse. Logitech definitely took reinventing the wheel literally—but in a good way by developing a smoother, faster, quieter, and a more responsive mouse.
