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
It took much longer for my laser to be delivered, I hope it faster next time. Have used my laser for three times, I feel happy with the overall quality.
No matter in any corner of the classroom, in the lecture hall, or in the back of the conference room with the listener, the screen will automatically appear on the screen, and the computer is no longer necessary.
Thank you so much for your extremely fast delivery. Got my laser within 5 days, amazing! The laser looks in good quality, I will see how it performs, and then give you more reviews.
One friend introduced me this website, it did not let me down. Bright enough to point to far-away objects.
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.
