F that, buy it and rip out the diode for a 50-100mw blu pointer.
A 100mw blue/blue-violet laser can burn the retina faster than a person can blink. It does not need to be direct "point" as a simple reflection is enough. This sort of retinal damage never heals and sometimes the victim never even realizes that they have permanant retinal damage.
Even a Class 3A green laser with an average power measured at less than five milliwatts causes permanant retinal damage, but not instantly it takes ~60 seconds. (This was proven by using a 3A laser on a woman whose eye was scheduled to be removed due to invasive cancer.)
The laser you are talking about is 20x more powerful but that does not mean that you can surmise that it takes 3 seconds of exposure to damage the retina. I have read but cannot qualify that a fraction of a second (faster than an eye can blink) exposure is enough to permanantly damage the retina.
If a person works with or around lasers stronger than a class 3A (5mw) I suggest that you search online for a "amsler grid print." You will be able to print an Amsler Grid sheet which looks like graph paper. With this you can detect voids in vision or other abberations such as inability to see the corners, or swirled areas (uh oh, the lines are straight).
Play safe and protect others. Different class lasers have different allowable uses, used wrongly and you violate federal law. If I see a blue laser in a movie theater I will (seriously) call the police and have the person identified because the highly reflective movie screen can cause un-noticable reflections that damage the retina. If it's your blue-violet laser probably your only cost will be about $100 for my eye test, of course others in the theater might also want a test...hmmm....how many people in the average theater...
In short, a laser pointer or any laser is like a weapon and should be used as such. The differerence here is that the green 3A is like a butter knife, and the blue-violet is like a machete. Throw one into a dark room and if it hits someone, well...
