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.

Other than a somewhat longer than normal amount of time to get here, I love this LASER. On low power lasers I usually give it the temperature test. I simply aim it at my palm or top of my foot and see how much heat I feel. You don\'t want to try that with this one. It will burn your palm rather quickly and the heat is uncomfortable on the top of your foot in a standing position.
Absolutely amazing. The beam is highly highly visible at night and in dark rooms, I could even track the beam outside in daylight.
It works great, fast shipping, arrived home about 10 days, good quality
Wow!!! Very powerful. In fact it's more power than I can handle. Wish I had opted for 200 Blue instead of the 400. Plus HTPOW Laser is the best in the business.
What can I say this laser is awesome! Would recommend it to anybody. For sure worth the extra money. Laser works up to expectations I had and even surpassed my expectations. Great buy and also pretty fast shipping especially it going across the ocean to get to me. Lot's of fun with it so far and looking forward to finding out even more things I'm able to do with it!
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.
