I had 2 lasers before from China. One was 150mW and the other 15W.
Both had no long lifetime and the 15W was lower powered than the 10W+ which I have now from Endurance-Laser. This laser from Endurance is so powerful that I have to run it very fast for a “non-cutting” job – or even throttle down the power over the software. It engraved an anodized aluminum plate 400% faster than the 15W laser from China – and the result was even better. The support is very good and I can say to everyone: ” Buy it and you will never be disappointed”
