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 recently ordered and received my htpow 200mW handheld green laser. I also ordered the safety glasses, the transmission beam fan, and matrix beam fan diffraction gratings. The reason I bought this was for pest bird dispersal. I have a very tall ash tree in my front yard, and when starlings decided to dwell there and leave dozens of acidic fecal droppings on my vehicles, on a daily basis, I decided to take action. Bird droppings can and will cause damage to a vehicle\'s paint. I didn\'t want to kill the birds, just chase them away. All it took was a few seconds of green laser light up in the tree to solve my problem. I haven\'t found any more droppings since my first \"treatment\". The birds are gone, and haven\'t returned. My family was awed when they stood behind me to watch. The matrix beam covers a wide area, while the transmission beam is linear. Of course, safety is the first priority, so the same safety rules that apply to firearms usage, apply to laser usage.
otra unidad mas que he comprado para compañeros... como ya he comentado buen laser bien accabado y potente aunque no tanto como para encender cerillas y demas.
This 5 in 1 Kaleidoscopic green laser pointer is better than I expected. With its exquisite and smart appearance, you can take it wherever you go. What surprises me is that so many stars filling in my room when using it. I'll purchase another one for my brother as a present.
The laser pointer was arrived at my house in Italy in only six days, and is very powerful and it has a very beautyful green beam. Thanks HTPOW Lasers.

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.
