If you are a frequent traveller who carries two laptops on working trips, like I do, the Logitech M720 Triathlon Multi-Device Mouse would come in handy.

This mouse can be paired with up to three devices. You can switch among these three devices quickly with the press of a button.

The M720 can connect to devices running Windows, macOS, Chrome OS, Android and Linux via an included Logitech Unifying USB receiver, or using Bluetooth.

For this review, I used my office laptop that is still running Windows 7 and my Apple MacBook Pro running the latest macOS Sierra.

The mouse is sculpted to fit your hand. It has a nice textured feel throughout and the contours allow me to rest my palm and fingers comfortably. There are contoured lines on its right for resting your fourth and pinky fingers.

The result - the M720 is one of the most comfortable mice that I have used.

The buttons are also within easy reach. On top of the thumb rest, there are three buttons sitting in a row. The front two buttons are for forward and back actions, while the last one is for toggle and connect.

On top, you get the usual left and right click buttons and the scroll wheel. Here, you will see the numbers 1, 2 and 3 labelled just above the toggle-and-connect button.

At its bottom, there is a power switch and the battery compartment. Open up the battery compartment and you will find the Logitech Unifying USB receiver slotted inside. You can use this USB receiver for devices that do not have Bluetooth capability.

To set it up, press and hold the toggle-and-connect button. When you see "1" blinking, proceed to pair it with your device.

To pair with a second device, press the toggle-and-connect button to switch to "2" and repeat the same steps as before.

Once you have paired it with three devices, just press the toggle-and-connect button to switch from one device to another.

I used the USB receiver to connect to my office laptop, as the mouse's Bluetooth Smart technology does not support Windows 7. For my MacBook Pro, I used the Bluetooth connection.

Switching from my office laptop to my MacBook Pro is seamless when I press the toggle-and- connect button.

This is really superb, as I need to take along only one mouse during my working trips.

I can switch between both laptops in a fuss-free way. This helps improve my productivity.

The battery life is supposed to be two years on a single AA battery. Plus, the mouse's buttons are supposed to be able to withstand 10 million clicks.

The only downer is that the M720 is quite big and might not be suitable for those who have smaller palms.

• Verdict: The Logitech M720 Triathlon Multi-Device Mouse is a great mouse to use for those using multiple machines, as it toggles seamlessly among the various devices.
