Blue lasers are actually the same type of lasers that are used in Blu-ray technology. Although it is rarely prefered to the green and red ones, it could be used for what others do, which also reflects the individual unique aesthetic taste. As far as presentation pointers go, it can be a nice change of pace to use a blue laser pointer, but much more powerful blue lasers are also available. However it comes down to all other uses such as pinpointing something on the large screen or on the blackboard.

Review List
This pointer pen works like a charm. It does just what it's supposed to do, and I've had no problems connecting it to different laptops for presentations. I like the USB device that lets the pointer communicate with the laptop. It's stored in the base of the pointer when not in use, and it's held in its storage port with a magnetic lock to hold it in until you pull it out to use with the laptop. It's easy to pull out, but it doesn't fall out by accident. The driver for this USB device loads almost instantly, and it works perfectly to move from one PowerPoint chart to another or to go back to an earlier chart. It's totally intuitive, and even an old dog like me can learn this new trick with no problem.
Really glad I lost my other laser pointer/presentation device. Otherwise I wouldn't have purchased this one, which is much better designed. Besides its streamlined design, the USB adapter fits snugly into the end of the pen. I can easily tell if it's missing just by touch. I teach in several different computer labs and classrooms and it seems at least once a semester I encounter someone else's wayward USB adapter in a computer.
Works great! Didn't need to install any drivers, and the design is sleek and convenient (the bluetooth connector is stored as a magnetic slide-in insert that fits the contour of the pointer -- clever!).
Use it everyday in presentations. It's good that you can switch it off on the side, so your battery doesn't get drained if you accidentally have something pressing on the laser button. My previous one always need battery changed because I just threw it in my bag and something pressed the laser button.
Blue Laser Pointers
Green Laser Pointers
Green laser pointers are now the world's most popular laser pointers, because the green light than red light 6 times more than red light beam significantly, while the price is much cheaper than the blue and yellow, green laser pointer is simply more powerful than red laser pen. Of course, this also means that green lasers are potentially more dangerous than red lasers. When operating this type of laser, it is important not to point it into anyone's eyes or to point it up in the sky towards any airplanes. It is probably not as much preferred lasers as an astronomy laser pointer, because brighter colors would make an object more visible in the sky.
Red Laser Pointers
Red laser pointers are by far the most popular and least expensive type of laser pointer. This is because the wavelength of the red color can be manufactured more easily than that of the other colors in the spectrum, red laser is also the only color that is available in the smallest size of laser pointers. Do remember that red laser light is powerful when it hits a certain object and converges into a point.
