The close-up laser module does a decent job of burning the perimeter, but not much beyond that. I bought this laser to add to my collection. They enforce the law and work night shifts, so have to be observed under different circumstances. This is very frustrating. First off, I have to say that you definitely want to check the battery before you do anything else. Most likely, the reason your green laser pointer isn't working is that the cells aren't working properly.
Is it because it's sold out or you're using the wrong type, I don't know. But if the repair is as simple as replacing a new battery, you don't want to go through the hard work of repairing your laser pointer. The laser acts as a printer where you can configure the power/speed/cutting/engraving etc, very simple. The only problem with these is the price. Pretty much remember, then you have to get air filters etc when adding the top. Laser scientists classify hazardous lasers by marking them with categories. Lasers that are completely safe and will not cause any damage to your eyes are Class 1 lasers.
While red lasers are still the most commonly used in homes, blue and high power laser pointers are growing in popularity. These alternative laser colors have higher power levels and you can use them for remote tasks. Green laser pointers are most effective in astronomy classes, while red pointers handle many everyday tasks. I have it delivered and ready to work, so I skipped that option. So I started digging into Chinese lasers... Chinese lasers sold by American companies. As far as I can tell, they're very similar builds, have similar characteristics (with the exception of size), and have similar controllers.
