As time ticks on I've noticed there's really not that much difference, if any, in the results of engraving like stuff at like settings. But one thing is true, the ebay laser is much louder than the Triumph when engraving. But I'm now attributing some of that to the very different lenses on each. That all said, seems power testing is really the only way to be sure...
