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.

So powerful laser point pen!It\'s of high quality and the appearance is very fashionable.You guys,don\'t hesitate to get one. I waited almost a month for this.There were backorder delays and delivery issued but well worth it. I was very surprised how bright and powerful it was.
I got this laser in the mail yesterday and the package had no bubble wrap and look like it went to hell and back but nothing was missing. the laser to 2 weeks for each laser to come and the first one was about a 30mw ir laser and they eventually sent me a new one.
The laser is well made and with aaa battery it has decent battery life. I have tested it on about 1 km (with communication with my friend) and the beam was still very bright and sharp. Not sure about burning, it is possible only if you focus the beam to very small point.
Item as described, arrived well and in nice box for packaging
It is good that the Laser can be locked with a key as it is very bright. I've not tried to light a match. Just wanted it for the lockable laser.
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.
