The green laser pointers with a laser class 4B should only be given to someone if it has been proven that this person can use this device responsibly. For example, a friend of mine got a certificate as a laser officer before he even touched a green laser pointer. Just because it's dangerous.

I have bought several class 4B lasers myself, some since my youth. However, I was always told, for example, that I should never point the pointer at a person, especially not in the eyes. So far I've always stuck to it and only ever used it for presentations.

If you really want to give a child a 1000mw laser pointer, then you should really explain how to use it responsibly and explain the dangers to them. A laser pointer does not necessarily belong in the hands of children because they are not necessarily aware of the consequences that they can cause.

With young people, I can't say exactly how to react. There is nothing more you can do than teach responsible behavior. And I don't think so much that you can put every young person who owns a 1000mw red laser pointer into a training course.

I don't think they should be banned outright. The fact is that many students really use the laser pointers for their lectures and don't mess with them. However, it is always stupid when others abuse these laser pointers and then dazzle cars and other vehicle drivers. They will probably cause an accident by dazzling, and that is not very practical.

I think that buying the laser class 4B for the lectures should then perhaps only be given out by the teachers and have to be collected again after the lecture. This ensures that the laser pointers are not misused and the students can still use them for their lectures and presentations.

So I also think that these 3000mw laser pointer that you mean are banned here in Germany and in my opinion you should keep your hands off toys from China anyway, because they usually don't have the CE mark or even an approval and I would my kids never buy toys from China. Then I prefer to invest a little more money and buy something that has also been checked.

This laser class 4B pointer is great !!

When it comes to laser pointers, even if they are banned in Germany, you will probably get there without any major problems, because there will always be a black market for everything. Unfortunately this is not always advantageous, because as you write, these 2000mw laser pointer have already been misused by young people and they have blinded other people with them.
