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.

Our 1-year-old cat is completely addicted to the laser-pointer! She\'ll chase it to the point of exhaustion, and then keep chasing it some more. The other functions seem more interesting to humans than felines, though. Charging it right out of the package only took about a half-hour through a USB port extension mounted to an electric outlet.
Love this laser! I thought this was one torch one lazer but you get two lasers that change to one or the other with an easy slide switch ,well designed and no hold down which makes fingers ache . A great gadget for cat play and for lectures or presentations as the torch part gives a nice perfect wide white light to show highlights and the laser for details. I’m a fan ! Especially as it’s AA batteries which are easy to find and use and not ware out so better environmental /green choice .
I know it’s meant for cats, but I love that I have white light, UV light, and a red laser pointer option all in one. I’m a physics teacher and this serves double duty as a laser pointer and a light source during our optics unit. I also love that it charges via included USB!
This laser pointer is so cool. The laser light is super bright and concentrated and it also has an option to turn it into a flashlight and a blacklight. Charges fast also.
Love that it uses a single AA battery and has a regular flashlight mode. Cats love it and I often have all 5 of them scrambling after the laser pointer.
Very functional. Have four days and having a laser for play is a must. Rechargeable means it is always usable. Adding in a two level flashlight is great. Hope it laasts!
Love that I don't need to hold down the switch to play, as some other lights require. Hours of play over months now without replacing a battery.
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.
