Cheap and ready soldered laser.
Laser is not so bright. Can not be seen good after like 4 meters. The spot seems a bit scraggy.
As with all DIY parts on DX there is no manual.
So I found out (searched the web) you have to wire minus to the pin labeled "-" and an 333Ohm resistor to "S" and then attach plus to the resistor. Without resistor the laser wouldn't stand a minute.
I don't know yet for what I will use my laser, but I think every (mad) scientist should have at least one laser.
