You're basing this on what, exactly? Do you have an equivalent product (e.g. a 532nm module, etc.) with which you did a comparison?i still go for o-like... they are better than rayfoss.
Be careful with the "focusable" lasers though, I have seen many people really disappointed with the green ones as they don't focus any "tighter" than the standard beam from any greenie, the "focusable" refers to the ability for you to focus the beam "out" like a flashlight or torch, that's it.
