I recently received my Laserbtb 980nm 800mW laser and so far I've been moderately happy with it. I paid $120.75 for the laser and ~$37 for DHL shipping. I ordered Friday and it arrived the Tuesday of the week after that Friday, (today) so like ~14 days (too lazy to add) :beer: It burns dark materials well, but can't even light a dark tipped match. 
I'm not sure why, but it doesn't even when I focus the burning point on say, a black trash bag. I suspect this wavelength is reflected more than others. :thinking: (yet another reason to wear goggles) Let me make another statement: the fact that this laser is completely invisible is terrifying. It takes special care to keep my eyes functioning.
So far this is my experience
Pros:
• Laser burns dark colored objects well
• Laser has lots of safety features
• Runs a while on batteries
• Has a long duty cycle
• Pinpoint focusable
Cons:
• The shutter is easy to forget to open because the beam is invisible
• Wavelength not easily absorbed by light colored objects
Another strange thing I noticed is that the little plug in the back of the laser is not required to run. When I bought the laser, I thought that would need to be inserted, however, it appears that a small metal piece already does the job and the plug is for remote control (according to the downloadable instructions).:beer:
Here are a few pictures. No beam shots for obvious reasons. In the future, if I make a youtube video I’ll link back here. And for safety I’m using my Eagle Pair OD4 190-540+800-2000nm goggles.:drool:
I don’t have a power meter available but it’s spec’d at 800mw. Here are the factory specs:

Beam Colour infrared
Transverse mode TE
Range in darkness (m) 300-500
M2 factor <1.2
Beam divergence,full angle (mrad) <6.0
Beam Diameter at Aperture (mm) <2.5
Spectral Linewidth (nm) <0.1
Polarization Ratio >100:1
Warm-up Time (minutes) <0.5
Operation Temperature (℃) 10～30
Storage Temperture(℃) -10～+50
Expected Lifetime (hours) 5000
Laser Head Dimensions(D×L, mm) Φ23.5 * 180
Cooling System metal heatsink
Operating voltage(VDC) 1*16340 battery
Warranty time 6 months
