Editorial Standards

Our goal is durable, transparent guidance—not product hype.

Source hierarchy

We prefer government agencies, standards organisations, occupational-health bodies, manufacturers for their own specifications, and clearly described test methods. Retail listings and unsourced summaries are not treated as primary evidence.

Comparisons

We compare categories and decisions rather than declaring a changing model universally best. Requirements, dimensions, accessibility, software, employer policy and local safety rules can change the answer.

Corrections and updates

Pages may be revised when official guidance, standards or technology change. Material corrections are prioritised over cosmetic refreshes.

Independence

Advertising does not determine conclusions. The site currently contains no direct product affiliate links. Any future commercial relationship will be disclosed clearly.
