Well said, I agree 100%.Nice review.
May I ask how you calculated divergence?
I have purchased several modules from O-like, and while the divergence is not as great as I would like it, I've never had one that was absolutely unacceptable (usually within 1.2-1.5mRad).
I think the modules are manufactured this way so that their burning abilities are impressive up close. This way, the average un-experienced hobbyist will feel like their module is more powerful.
Edit: Regarding power output, I have found that the 130-150mW modules generally output at least 110mW of pure green. I have one here that outputs 140mW+ un-filtered and about 110mW filtered on 3V CR123A. Not bad at all, in my opinion.
Don't be too disappointed... remember that we buy from O-like and similar companies because they provide cheap power and good customer service, NOT because the products are exceptional in every aspect.
The rule still applies here, you get what you pay for, and in this case, you are paying a decent price for a decent module.
And every now and then, a bad unit is produced. That is unavoidable.
I am trying to integrate a 200mW green module into my budget plan... it won't be anytime soon, but when it will, I will order it from o-like for sure.
