>EDIT opon taking the lens of and looking at the diode i see what appear to be muiltimode lines like my 808 has. They said the rated current was 650ma and it only uses 420ma.
I got this about 2 weeks again and I'd say It's been great so far as I can see the line in a dark room without adapting to darkness and it's a sky blue line. This is the same seller that had the 980 pen.

Got here in under 3 weeks from china before the estimated date.
Laser build
9/10
It's a standard style 6 volt laser. Could of been made to run of one battery and not 2 3.6v as it makes alot of waste heat. Generally IR lasers can be ran more efficiently.
edit I just tested it on my lab PSU. It draws 420ma at 3.15 and at 6.5 ish. The light dosen't change but 3 volts makes alot less heat.
Beam quality
6.5/10
I haven been able to get the divergence down below 2 ish mrads
turns out after looking at it on my cam carder it looks like it has muilto mode patterns with no lens on.
seeing how the beam only focuses into the line it supports this theory even more.
Overall 8/10
I would rebuy this since my samsung camera camcorder works like intend and it can make a night NV device. It picks up 980nm much stronger infact and is able to autofocus it like my 1 watt 808nm with no lens.
here are some shots/ stills from my camcorder
980nm laser - Album on Imgur
The wall was about 15 feet away and the switch about 9. I have no idea how bright the beam was there but you can clearly see the irregular beam shape on the wall just like in that picture my camera which was zoomed in all the way. I suspect they may have put a muiltmode 980nm and under driver it or do they just have bad divergence?
