Hello my friends!
usually i write about flashlights - but todayi do something different…
today i tested a
Banggood sent me this one “(shoplink)”:http://www.banggood.com/LT-HJ-532nm-650nm-Green-and-Red-Laser-Pointer-1mw5mw-2AA-p-953734.html
and i got what was promised (not usual in some Chinashops ;))
backside of package and safety instructions
a look inside with the second set of batteries - the delivered ones worked fine! (more later)
the Pointer
its made from athin aluminium tube with a rubber-ish coating
but at some points it starts to come off
the batterie side - since the positive tip touches the bottom there is no spring needed
the driver side - there is some foam to protect the electronics…
the bright end
the red diode is the one on the outside - the green is hiding inside the Pointer
the “caleidoscope” lens easy screws on top
only the blank ring has threads - the part with the knurling freely rotates (and make it a bit hard to mount the lens
BEAMSHOTS!
(Sony NEX-3 in manual mode, ISO800)
reference:
guess…
different settings…
distance 125m
some videos i took:

Kaleidoskop
my thoughts:
this item is NO TOY!
keep away from children and stupid people!!
its very bright!! (rated 5mA - consumes 300mA from Alkaleaks!)
a friend (experienced with lasers) thinks 150-200 mA of output
due to bad focus or cheap lens it cant burn anything…
(ecept retinas i am sure!)
the Laser has 4 modes:
(off) - GREEN - RED - GREEN + RED - GREEN + RED flashing - (off)
the button cycles through them…
unfortunately the laser has no ON/OFF switch - i managed to accidentally switch it on in my pocket. thats why the first set of batteries emptied 
feels not bad in the hand - the rubber-ish coating is nice
