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.

Good laser pointer for what you\'re getting. Has a powerful green beam to where you can see the trail in the dark. My only complaint is that it does run out of battery fairly quickly, can last about 15 minutes on two brand new AAA batteries if using quite frequently.

Very nice. Could have inserted information on battery installation (polarity)
Some initial problems with packaging, but the seller handled it quickly and efficiently. Light is (pleasantly) brighter than I expected. My dog loves it. Be very careful not to shine it in eyes. It reminds me of a Star Wars light saber only smaller.
The laser works great for what I needed it for.
There's a limit to the strength of output that can be sold commercially in the US. As most readers know, for some reason green light lasers have been maliciously used by a handful of people trying to shine in eyes of commercial pilots on landing or takeoff. This is so malicious it should be a felony if it isn't already. Anyhow this gave by far the brightest beam I've personally seen from a hand-held laser (it uses the maximum allowable voltage). I haven't tried seeing how far it could hold a visible spot outdoors at night--I was interested in in-home use-but in the confines of a home, the beam is quite bright even in the daytime. Do not shine this near your pet's face or any person's face, it would probably be harmful to the eyes at near range.
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.
