Do I need eye protection?
Yes. Use glasses rated for the wavelength of the laser you buy, and never rely on the enclosure alone.
Can it cut metal?
Diode lasers mark some coated metals; fiber lasers cut and deep-engrave metal. Check the listing’s stated capability, not the wattage alone.
What about fumes?
Vent outside. Cutting plastics and coated materials can produce harmful fumes; never cut PVC.
Who handles the warranty?
The seller on your receipt. The channel comparison shows how that changes between routes.
Are the specifications tested by you?
No. Power, work area and software are what the listing states. We mark them as listing claims and we do not invent figures.
Why does a page say “check live price”?
Prices change and we do not republish figures the seller controls. The link opens the current listing price.
