I confirm, it's 100% not safe as the front of the audience was greatly at a shorter distance than 60 meters ! Take a look on Google Maps, where the event happened :

But this isn't the worst of their shows... take a look at this one :

Audience is only at 6-7 meters from 2x 8W low divergence green OPS, 1x 20W RGB and 2x 8W blue (they advertise they only have kwant projectors but these blues come from OPT, shhhh it's a secret
).
And no beam attenuation map.
Here too (don't be fooled by the "6W" description, they only have 8W green in stock) :

Only 3-4 meters distance. Poor people
.
This company started by November or December, 2013. It has been launched by 3 guys who don't have any technical knowledge (they were event planner before). As they already have a main work (job in an other area), they do laser like a kind of hobby with money for lasers coming from the first job. I personally have nothing against that.
However... these fuckers gave some hiring offers here in Belgium for 1x 20W RGB, 2x 8W OPSL and services for 3-days for 1250 €
.
They just kill the market and the eyes of the audience.
If someone start to tell them it's not safe and price are too low, they only reply "you have nothing to told us, we use kwant laser" ...
