Kids, if you are looking at this drop and want to buy a lazer for fun, DONT. 2.5W is a pretty high wattage for lasers, and could easily blind you if you aren't careful. I hope the 12 people that have bought this drop know what they're doing and aren't careless. Besides, if you just bought this to play with, its probably going in your closet collecting dust within a week. It's not worth risking your sight for this.

VicturtleBy "easily blind you" what he means is that since my 1W 445nm laser can permanently blind you in less than 0.25 seconds from 400 meters away, this thing can do it in less than a tenth of a second from the same distance. Imagine how much faster it could happen if you took even an indirect, reflected flash from inside your room. Something tells me you won't be lucky enough for the beam to have reflected around for half a kilometer inside your bedroom.

TipsyMacScotchslurpenfaster -> swiftlier -> sooner; won't -> shan't My room, minus the mirrors, lacks the flat specular surfaces to reproduce the beam. Besides this kind of beam should evoke a blink reflex.

alysdexiaI mean, by all means, they are your eyes, so think what you want. Even if you spread the beam out and a goodly portion of it is lost to random surface reflection in directions that don't hit your eyes, you are taking a "maybe" tiny amount of the original beam power, but the beam also didn't have to travel 400m. Regardless of whether the wavelength falls into our visual spectrum and can cause us to blink, the average human "blink reflex" is about 0.1 seconds. So, if someone was 400m away and they were able to reliably hit your eye with the beam, you would be blind before your eye closed. I mean, yeah, you're not taking but a portion of the full power of the laser if it reflects off of a porous/matte surface, but you are also only 2-5m away. I wouldn't take my chances. I'm not saying that you shouldn't buy the laser, I am just advocating for proper protective eyewear. Make sure to get a pair of laser safety glasses/goggles that protect against the range of wavelengths that your (this?) laser falls into. Make sure that they are rated for the power output of the laser, and make sure that they are made by a trusted manufacturer (there have been cases of substandard or even fake laser safety glasses being sold on pretty much every popular internet megastore (like Amazon and eBay), so be careful.
