    I like the unit, great price and runs of a single LiPo or a USB 5v output It is however not collimated, I guess like all LED laser/monochromatic light sources are. The first photo shows it at 8m rear projected onto 1cm graph paper. Then I took it apart and had a look, as you can see you have a focus lens and a cover, and the LED assembly is much smaller than the tube. I adjusted it and got it to the final photo, a bit over 1cm in diameter. I might end up tuning it more, but it is possible. It is very

    reçu et contrôlé, un laser ok mais l'autre hs. Faisceau avec des imperfections mais dans l'ensemble content. La divergence est assez grande mais tout dépend de l'utilisation qu'on veux en faire. received and checked , a laser ok but the other off. Beam with flaws but overall happy. The difference is quite large but everything depends on the use we want to do .

    Well, I unpacked the module tested it with 3.7 volt battery for a second and it lit up. Then i saw some dot (dust) sticking to the inside of the lens. Opened it and saw i couldn't reach it (need paint brush) so started closing it again. While turning it the laser part fell out of the bottom. The laser and DPPS part split (if i identified correctly) when hitting the floor. There is a green chip like miniature plate at the bottom of DPPS part that looked damaged. Anyway i had a go at mending it with

    I had to adjust the focus of the laser to achieve the 14-16mm green dot as specified, the dot was initially about the size of a squash ball at 15m. This is no problem and is easily accomplished. The laser beam is very bright, the label states: class iiib, which means that one should wear protective glasses when there is potential of eye contact. A small issue that I do notice is that the beam goes dim after a minute or so of use on a fully charged cgr18650 battery. It seems that the current controller

    Ok But a few crystals came of. either badly glueed or rough transported. I could fix it my self wearing automatic Welding glasses but won't recomment to others to do so. BE AWARE CAN CAUSE BURNS AND BLINDNESS. the LASER can burn dark surfaces if crystal is detached!!!
