The laser is working really really good! Is it really up to 30W, I'm not sure based on some other people tests, but It doesn't really matter and I won't even bother to test, because it's among the best anyway (that are way pricier) and the results are there, it does cut and engrave like a pro. Was able to put it on my own machine without issue (workbee 1010 variant + g2Core)
