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 have not had them that long but so far I'm very happy.
This website has the lowest price anywhere and shipping is free. Cant be beat. Batteries came quickly and worked as expected. Will buy more for other devices when I need them.
Works perfectly recharging batteries.
So far having no problems with batteries. Mainly used on wireless keyboard and track pad (both apple), remote control, and Xbox One controller. Uploaded two pictures (first four and second Four)with the fully charge mAH doing a refresh/charge process.
I love these batteries for my flashes. They're inexpensive (for rechargeables), they're high-capacity, and they're reliable. I'm a professional photographer and I go through a lot of batteries in my flashes and triggers (among other things), and I have Eneloops and a variety of other brands. In my tests, these are truly 2400mAh, unlike many cheap brands out there on the market. So, they're giving me 25% more charge at the same price (or less) than Eneloops.
I have 4 solar powered spotlights in my backyard that were no longer performing as well as expected and it was 12 of these batteries that I ended up purchasing to once again restore them to life. These batteries definitely did not disappoint and are far superior to the batteries that are included with many of the electronic products purchased nowadays, my solar spotlights included.
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.
