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 received my order as promised. The 200mw laser is definitely more robust and powerful than than the previous 200mW that I purchased which by the way stopped working after only 1 year of casual use.
Review List
Came with battery and charger,very satisfied! The laser beam light goes very far and is very bright. It's a fun to play around with it at night.
L'involucro del laser è in alluminio, il che da un senso di robustezza. La presenza della batteria al litio e del relativo caricabatterie ne rende immediato l'utilizzo. Inoltre l'attivazione mediante chiave, rende l'utilizzo del laser sicuro, specie in presenza di bambini. Visto la potenza non trascurabile del fascio emesso si consiglia l'utilizzo di occhiali protettivi.
Given how cheap it is, I figured it's likely that it would be dead when arrived. But in fact, the laser pen works GREAT! You can clearly see the beautiful light out of it. An awesome product.
Dieses Produkt übertraf meine Erwartungen für seinen sehr niedrigen Preis. Das Instrument hat einen gut gefertigten Aluminiumk?rper und ist damit der perfekte Laserpointer. Es war das Warten wert. Ausgezeichneter Wert!
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.
