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.
Great quality product with very strong beam. Nice box. Fast delivery. When I used this product I was surprised on how good it is and it is a really powerful laser as well.
I've ordered a total of 8 of this particular laser over the last few years, and they work great great. This design is sturdier than the all-black case version, so I recommend this model.
The laser itself is well made, the beam is solid and straight, the range is impressive and the battery life is extensive. The pen clip part of the laser pointer broke off withing 20 minutes of me opening the package, and the case was a little beat up probably shipping problems, but otherwise, the laser is a decent find for an amazing price.
The prices and items selection were outstanding.
Good for playing around, should be entry laser for most. Hope you get one for your self. you will love the power it has in a small device. Be safe!
Highly recommend. Have bought 5 of these during the past 6 months. They consistently work well and still going strong. Sturdy casing. VERY bright and can slowly put a hole in dark plastic. Don't buy this for burning though. Give them to trusted friends as gifts, they'll LOVE them. Average people don't know you can ever "see" a laser beam. These things are a huge hit! You cannot beat the price.
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.
