Separate experience from a measurable promise
A viewer can honestly say that a programme played well on their television. That describes their experience under particular conditions. It is different from a claim that a service always delivers a stated resolution or works on every device. CAP’s testimonial guidance says factual claims do not stop needing support simply because they appear inside a customer quotation.
Look for the conditions behind the account
A useful viewing review identifies the device, application, connection and period tested, without exposing private credentials. Even then, one setup does not establish a universal result. Ask whether a performance claim is supported by a relevant measurement or merely by a selection of favourable comments. The review’s authenticity and the breadth of the inference are separate questions.
Read star summaries with their scope
A rating can summarise customer opinions about several aspects of a service, including support or ease of use. It does not automatically measure technical image quality. Check the source, date and what reviewers actually assessed. Do not invent an independent test, average score or endorsement from an attractive testimonial card or a brand logo.
Use reviews alongside the right evidence
For a household choice, combine relevant experiences with the provider’s actual specifications, terms and an authorised viewing test where available. For a complaint about an advertised technical promise, retain the precise claim and its supporting context. CAP’s point is that objective statements need appropriate support; it does not mean every subjective preference must be treated as a laboratory result.
