Several tests with 5000mW did not give the expected results. With this range, I must pass without problem with the CNC. The product is well finished, with its adapter and converter for EU plug. Great, keenly the first tests. In addition, it comes with the appropriate glasses because the light density is really higher. We can never say it enough ... ATTENTION TO THE EYES ... The work surface is not perfectly flat and can sometimes reflect radiation, the damage would be irremediable to the eyesight. At this power we have long since left the toy stage !!!!
