#laser I will come back and update using thelaser gun( https://www.laserpointeur.com/c-40_77_79-p-10133.html )if I remember correctly. I updated my review to 4 stars instead of three thanks to customers who clarified me on some details where I was wrong. For the features and everything that comes with it, as I said in my title, “it's worth it for the price”. It contains a powerful light. I like the fact that it is adjustable from the laser flood to cover a wide area or focuses on a projector. The charging unit seems to be well done and the additional battery holder which is an excellent support.

Some laser guns are better one than the other, but it works equally well for both. The beam is adjustable for smaller or wider areas. I love it comes with a rechargeable battery and a charger for it! The compact size is nice for women, as you can easily carry this USB laser gun in your purse without taking up much space. I'm never a fan of the strobe capabilities of lasers, especially when you have to go through all modes to disable it. A little training in its use, disabling and enabling switching modes will be useful. I liked this one so much that I bought three in total for the house and cars. I am more than satisfied with this purchase. Trust the critics of this great package.

La laser diode has a quality construction and works as advertised with the exception of the output which is more in the order of 600 MW. However at full focus, the narrowest beam, it fails because of its design. JETLASERS customer service contacted me a few days ago about my original review. They offered to send me a replacement product instead of the first one I bought. The new unit works perfectly. I tested the replacement laser and did not encounter any of the mode changes I've experienced before. But above all, JETLASERS has proven to be a very customer-oriented company that values satisfied customers. In the narrow confines of the room, I could not see any difference in brightness with the lens in either position. Pushing it the first time reduces the power of the laser. Pushing it again reduces it again.The beam, when concentrated, gives a strange pattern on a wall, it is square and has 3 or 4 horizontal lines that cross it, it seems that you project through the diode, very strange. It works well like a projector. I have other cheap laser diodes that are better, but this rechargeable battery saves this thing from unwanted draw. This function alone, simple on/off, distinguishes it from all other lasers in its price range and class.I would give to this laser power meter a 5-star rating for brightness, but the circuit that controls the functions is terribly fragile. Modes are great additions, but have made unity a danger to safety in my work. The laser will randomly switch between modes or turn off completely. I've been seeing these lights in web ads for a few months and wanted one. I bet the laser pointer I bought and the one sold for three times the quantity were made in the same factory! I was pretty impressed with the packaging and extras provided with the light. It also comes with a charger. Even if it does not come with AAA batteries, it has the frame that holds them together.It protects the lens and prevents it from scratching when the laser power meter is standing. I learned hard when I installed the battery to see if it was charged or not. It turns out this is the case AND the laser pointer switch has been activated! Unfortunately, I was looking at the lens when I re-screwed the switch cap. After clearing the spots from my vision, I went to a guest room with the blinds down and the door closed to play with her for a little while.Users with higher output power selected, users can simply get even brighter and visible cross lines in operation. At the same time, optical accuracy may become lower while the laser pointer for presentations works in high-brightness work environments. Whenever users make precise optical experiments with this industrial laser, users should always be quite careful with powerful laser radiation. I tried adding an extension tube from another laser pointer and used an 18650 battery. The beam is very powerful and completely uniform. And it projects the light over a very considerable distance in spot mode.

It should be a wonderful decision to do research with a laser pointer for presentation during a long working distance operation. Usually it is not realistic to make measurements with a simple square meter, a triangular meter. Most of the time, users are severely limited by the exact targeting distance or height of these manual operating tools. However, the powerful laser has just projected a super bright and visible laser beam onto high-visibility, high-brightness targeting surfaces. It is never permissible to make directional laser radiation and laser reflection in human eyes. It gives you confidence that it will work every time. https://www.starnow.co.nz/laserpointeur
