The computer mouse is probably the device we handle the most after our smartphone.

Yet, I find it amazing that there are many who can tolerate a standard office-issued and usually not-very-good mouse. I can't. That's why I always use my own mouse at work. And that's why I will be getting the Logitech MX Master 2S.

This is Logitech's flagship mouse. Its ergonomically sculpted shape and large thumb rest supports your wrist in the most natural position possible. This is one of the most comfortable mice that I have used.

But it is designed for right-handers. So if you are a left-hander, you might want to pass it up.

The MX Master 2S has eight buttons. On its top are two click buttons, a scroll wheel and a Mode shift button. On its left are the back and forward buttons, a thumb rest which is also a gesture button, and a thumb-scroll wheel for horizontal scrolling.

To make room for this convenient thumb-scroll wheel, the back and forward buttons are sited a tad too far behind. I always have to stretch my thumb to reach them.

To use the gesture button, press and hold down the thumb rest. You can then move the mouse in up-down-left-right directions to execute different functions. For example, if you set the gesture button to control volume on your computer, moving the mouse up increases the volume, while moving it down lowers the volume. Also in this setting, moving the mouse left or right will move back to the previous track or skip to the next track, respectively.

At the bottom of the mouse, there is a power switch and an EasySwitch button with three LED lights. This mouse can be paired to three computers, via either Bluetooth or the bundled Logitech Unifying Device USB dongle.

Pressing the EasySwitch button will toggle the mouse through these paired devices. And it is really quick when changing control from one computer to another.

The MX Master 2S has a 4,000 dots-per-inch sensor for tracking accuracy and is said to be able to work on any surface, including glass. But the glass surface needs to be at least 4mm thick. It worked perfectly on my glass-top dinner table at home - finally, a mouse I can use there without a mouse pad.

The biggest highlight of the MX Master 2S has to be Logitech's Flow function.

According to Logitech, this feature enables the mouse to be used with up to three computers at the same time, whereby you can move the mouse cursor from one computer to another, and even copy and paste documents across the connected computers.

However, Flow did not work in tests with my iMac and Windows 10 gaming rig at home.

But it worked when I linked the mouse up with my iMac and MacBook Pro (both on macOS Sierra). I can copy and paste a picture from my MacBook Pro to my iMac seamlessly as well.

The MX Master 2S uses an internal rechargeable battery that can be charged using the micro-USB port in front of the mouse. I would prefer to have an AA battery option. But a full charge is supposed to last 70 days and I have yet to recharge it after four weeks of use.

• Verdict: The Logitech MX Master 2S is the ultimate ergonomic and productivity mouse that money can buy. It would have been perfect if Flow can work properly across all the operating systems.
