There's no way that that thing is 2 watts at that price, battery size, or host size (unless the duty cycle was small).
That doesn't seem like safe logic to me. 200mW is dangerous even if we have 3+ watt lasers. Just because it is lower powered doesn't make it low powered.

That is cool! +1 from me!
A laser terms dictionary would be good.
That sucks that it got rejected. I've been there before. You can appeal, and they are nice about it usually.
While we're on this subject, I would like to share a message I received from lasersbee on 7/29/13 after I left him a -rep.
I personally agree that name calling is not scientific evidence, and is uncalled-for.
In the interest of full disclosure, lasersbee later apologized.
