I would be happy to do a review of this laser for you. Given the previous experiences we have read about high powered lasers from this company it may be a good idea to rebuild some confidence by showing a video of this product being tested on an LPM with and without an IR filter. Also maybe a test of divergence showing the spot size on a black surface at 100ft and 50ft. Maybe measure the current as well. Just some suggestions. Price looks good but now it is time to establish quality.
 
yah thats the only way i would consider buying a yotang laser is if it was reviewed by a vet.....yobresal would be great for this !!!!
 
The goggles certainly don't look promising. They look like the ones I bought from china that only block 50% of green laser light... Which would basically be useless for this power of laser. It would be nice to get the goggles tested too by yobresal.
 
It is almost impossible for each company or each person to be not making a single mistake.If someone had made a mistake for once ,can we completely deny him? Obviously not, we will strictly control the quality of our products in the future, and try to make sure everything is right!
 
Looks cheap to me, if I was to spend that much on a laser I would definitely need to see it tested by someone first. China isn't exactly known for its great quality :D

CNI comes from Changchun. Nearly all of the lasers we buy are from China. Some factories just do better than others.

LPF is LaserPointerForums, which is here :p. There are many people here with the ability to test your laser for you on their power meter and look over the quality, a few that members that come to mind are Kenom, Yobresal, scopeguy20, Jayrob, Daguin, all are well known and trusted here. Hope it helps.
 
Trend Micro Worry-Free Business Security Advanced Edition blocks yotang.com, listing it as a dangerous site. Maybe previous owners with same IP were less-than-honest computer-types, but either way, careful when navigating this page. I doubt that a hacker would target laser enthusiasts, but who knows.
 
I'd test it out.

Do you have a laser power meter? A review of a laser from a new laser company would be kind of useless coming from someone without a power meter.
 
I think the best way would be to make hard guarantees on performance: Say, at least 450 mW in the first 30 seconds, and 400 mW after 5 minutes of runtime in a room of some specific temperature.

There are plenty of reliable members on here with decent power meters that can perform the tests, and probably do that free of charge if given the chance.
 
Seems to me that this Seller is not willing to invest in a review
of his Lasers on our Forum...
I guess +10000 Laser interested members is too small a place to
make any $$$.. or the Lasers are not up to snuff...:undecided:

There is no way I'm investing over $400.00 for an unknown Laser
to do a review to help their sales..:cool:

They should perhaps go the way of WL for testing...:whistle:
