Pros
  • 48 W cuts thick wood and acrylic in far fewer passes than 10 to 20 W machines
  • Switches to a 24 W mode for finer engraving detail
  • Air assist comes in the box
  • A low price per watt
Cons
  • Open frame Class 4 laser: goggles, an enclosure or a vented space are a must
  • No camera or autofocus
  • The high power makes smoke and fire risk greater, so never leave it running alone
