How we research

We compare devices on documented specifications, regulatory status, and listed capabilities — not marketing claims.

Editorially independent

Some links earn us a commission, and we disclose that on every guide — but it never changes what we recommend or how we describe it.

Plain English

We translate clinical and technical detail into clear guidance any reader can act on with confidence.
