Everything comes from China products reviews site purchased in China
This device is basically a small laser pointer with a USB receiver that serves to make presentations in PowerPoint. It comes in a box shown below:
To make it work in your computer or laptop you must put the receiver in the USB from your computer. The drivers are installed automatically in windows 7 or XP.
After you press the arrow keys up or down, the laser pointer shown below, and the receiver will produce the same effect as a page up or page down on your presentation.
For easy transport, the product comes with a carrying case that can also be used to load the Flash drive with the presentation.
Below you can see the imitation leather carrying case. Pretty good quality.
The power of the laser pointer is made by two AAA batteries. Interesting is that the product comes with batteries.
The laser pointer is totally independent of the USB receiver, being strong as shown below.
As soon as you put the USB receiver to your computer it will start blinking indicating the driver installation. The LED also flashes to show that a slide is being made.
The computer recognizes the product as a USB composite device, very similar to a keyboard.
I made a video showing the use of the product, check it out below:
