^^ yip thats why they give you the glasses.
Very dangerous though as you said. If you point it at the wall or something and arent wearing the glasses even just looking at the light makes your eyes go wierd for abit.. you keep seeing the flashes of the beam/light once its gone.

That's called minor ablation of your retina (or other parts of your eye) and it's permanent damage.

Sorry to revive a dead thread, but just in case anybody was interested, I got my laser today (same merchant as OP).  It seems about as bright as one I got about a year ago for $12.  That means it's among the brightest lasers I've ever seen, but I've never seen an expensive one.  Here's a pic of the warning label.

Can it burn stuff?

As a side note, I guess he really did make a genuine mistake in sending me a broken laser.

The factories that make all these cheap electronics have really bad quality control procedures, roughly 5% of the stuff they sell to wholesalers is DOA and quality varies greatly, buying these cheap electronics from China all depends on how lucky you are, if your really lucky you'll get some amazing way above-spec product, or you could be unlucky (as you were in this case) and get something that is DOA.

Ok, I'm not gonna bother the guy.  He seems innocent enough.

Once the chinese figure out what people mainly look at specifications wise on a certain item, they'll usually jack up the numbers as much as they can. In this case probably an order of magnitude more than what the laser can actually do. They know someone will see the inflated numbers and buy one because it's cheap. Most people buying green lasers online haven't done much research on the subject, let alone purchase a laser power meter (mine cost over $1500) but I do a lot of work with lasers on a regular basis so I could justify spending some cash to get a meter that is certified and calibrated by NIST standards.
