Hello, i have some questions about these lasers:
1. Is IR important and less safe?
2. I have seen on DX True Green Lasers like this one. How does it compare with this one?
What does true mean? Non-counterfeit laser?
I mostly need green laser for pointing at products in stores, pointing at objects, maybe for presentations and less for pointing at stars and playing. I need a safe and affordable normal quality green laser that is around or little over 10cm. The one with focus would be preferrable unless considerably more expensive.
Cheers!
