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.

I was searching for a cheap but good laser and this was my choice. The key to block it for children is a great bonus. It works well, it is really bright, but I think it do not have perfect focus. At small distances the dot is a bit squashed, not circular. At great distances the dot becomes really large. I estimate that at 100 meters the dot it at least 10 cm. At night the beam is not visible. I have not tried to burn anything so I can not tell anything about that.
Great quality product, I am very pleased with my laser pointer and will be ordering another one!
I bought the red laser to add to my collection it really performs great. The beam is very thin and has a bright red orange color dot and it travels very far. the duty cycle is long and it barely gets warm i love the spartan host its very cool but simple i wont hesitate to buy here again htpowlaser is the best.
This red laser suited all my needs. I have to align optical eyes that are over 100 feet from each other no problem seeing my mark with this laser. Very reliable, excellent construction.
Great product. Smart packaging.
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.
