I ordered two keychains from them. One was damged and the other (with 42 patterns) worked, but the case was also broken.

But this 405nm in the Aquarius housing looks interesting:>>here<<

Looks like typical mass produced chinese crap, the domain is even registered to a chinese shipping company based in Manchester - Drop shippers anyone?

From its item description:

To get blue laser light first you need an infrared laser which pumps a crystal ,this in turn pumps another crystal , which pumps another crystal, in order to get blue light at our our eyes peak sensitivity of 405nm , Because the optics used for generation of blue laser light are less efficient and more expensive than those used for green, blue laser diodes are still expensive but hey ! at least they are available !!

I laughed.
