Serious cutting power for the price
Went from a 10W diode to the Ray5 20W and the difference is massive. Single-pass cuts on soft woods and clean acrylic edges (with air assist) at a fraction of CO2 costs.
Powerful but safety is on you
Treat it like a true Class 4. I built a fire-resistant enclosure with proper ventilation and it’s been great, but I would NOT run this unattended or in a classroom.
Firmware/UI feel unfinished
Touchscreen typos, Wi-Fi doesn’t auto-reconnect, and I hit a few USB ‘Hard Limit’ errors. LightBurn workflow is fine, but the onboard software needs polish.
Misleading safety claims turned me off
Seeing Class II claims on listings for a 20W open-frame laser was a red flag. Returned it and went with a more refined system that included an enclosure.
Great value, but manual focus slows workflow
Cuts like a champ and color marks stainless beautifully. Manual focusing between material swaps gets tedious. Add air assist—essential for consistent results.

Conclusion
The Longer Ray5 20W offers exceptional cutting and engraving power for its price point, making it a strong choice for budget-conscious hobbyists. However, its value is offset by significant safety concerns and a lack of refinement in its software and user experience.
