I hesitated for a while before buying it. After all, it is a lot more expensive than any other device. But in the end I am very happy with my purchase. From the moment I took it out of the box I had a good feeling about it. The package. The attention to detail. How the USB receiver is built into the bottom. How is a USB-C hidden under it. And of course the fact that you can present hours with just 5 minutes of charging.
I regularly give presentations or lessons to groups of more than 20 people. Not everywhere I go there is a large projection screen available. So being able to zoom in on certain parts always comes in handy. (If you do this with a moving image, it takes a kind of screenshot instead of enlarging the video.) You can also control the cursor from where you are standing. so you no longer need a mouse to click on links and buttons in your presentation.
It is also very nice that the software works as a layer above your screen. And therefore works with Keynote, Powerpoint, Prezi, Chrome, Photoshop, ... The spotlight also works fine for large auditoriums where your laser pointer would disappear, since it works with software and you can adjust and scale it as desired.
Finally, there's the timer, which I personally use less, but if you're presenting without a monitor, it can vibrate subtly to help you finish your story within the given time.
In conclusion: yes, this device is more expensive than all other devices. But it is not a device like all the others. This is a totally new and better way of presenting. A new generation, both in ease of use (software, spolight/enlarged features) and in reliability (battery, usb-c, supplied cable, bluetooth support, ...)
