Editorial Policy

How we separate documented claims, analysis and hands-on experience.

We do not claim hands-on testing unless it occurred and is specifically described. Manufacturer and marketplace specifications remain claims tied to an exact model and source. We avoid static prices, invented ratings and copied settings. Material capability is described cautiously because wavelength, formulation, finish and process goal change the result.

Scope and responsibility

Content is maintained for research and comparison. Product listings, manuals and material formulations can change, so readers should verify the current source before acting. Safety-critical questions belong with the manufacturer or a qualified professional familiar with the exact equipment and process.
