Review verdict#3

The AF400UK is a strong, mature dual-drawer all-rounder, but one test found uneven fry browning unless food was shaken repeatedly. It is placed third and that conflicting result remains explicit.

About this result
Secondary specification scopeEligible for specification comparison
Purchase adviceNot currently supported

Secondary specification rank #7 compares published inputs inside the tracked category cohort. It is not the review-led quality result or a reviewed instruction to buy this product.

Candidate-set and method sensitivity are now retained for this leading cohort. They do not satisfy the missing evidence or human review gates.

  • independent exact model evidence missing
  • controlled measurement missing
  • safety not structured
  • claim level trace missing

What matters, what we know and what is missing

Open evidence report JSON ↗

This is a specification-ranked comparison report, not purchase advice. It uses the category evidence profile below and keeps hands-on findings separate from the published specification score.

Primary real-world questionCooking evenness

Documented cook tests showing browning and doneness across the usable basket.

Hands-on synthesisnot collected

No exact-model hands-on synthesis is published. This report covers sourced comparison inputs, coverage and open gaps; it makes no claim about real-world performance beyond retained sources.

Specification rank#7

Inside the bounded published category method.

Stress-test range#3–#8

Cooking evenness

Documented cook tests showing browning and doneness across the usable basket.

Hands-on state: not collected
Cooking speed

Timed comparison using disclosed food, load, preheat and programme conditions.

Hands-on state: not collected
Usable capacity

Hands-on load evidence, not nominal litre capacity alone.

Hands-on state: not collected
Temperature accuracy

Measured temperature stability and recovery under a disclosed method.

Hands-on state: not collected
Smoke and noise

Direct observation with food, temperature and room context.

Hands-on state: not collected
Cleaning

Repeated hands-on cleaning evidence covering basket, tray, seams and dishwasher use.

Hands-on state: not collected
Controls and safety

Direct evidence on controls, hot surfaces, stability, shutoff and handling.

Hands-on state: not collected

Hands-on gate: Require the exact variant and at least one documented cook test with food, load, mode, temperature and elapsed time.

Decision cruxes
Cooking evenness

Published capacity and modes do not establish like-for-like cooking evenness or browning.

Usable capacity and cleaning

Nominal litres do not fully describe practical food area, batch size or cleaning effort.

Normalized decision receipt

7 mapped fields each carry a canonical receipt hash and an origin status. Source access time is kept separate from field observation, so a configured value is not presented as freshly re-extracted.

The score and rank compare retained specification inputs inside this bounded category cohort. They are not a hands-on quality verdict and are not comparable across categories. Open evidence gaps block purchase advice regardless of specification score, rank, offer state or review-synthesis verdict.

Source notes and limitations

Evidence limitations

  • Published specifications are not Agent Review Data laboratory measurements.
  • The manufacturer-direct source offer and availability can change after the checked time.
  • Exact model identity is keyed to the model/SKU in the source register; related colours and bundles are not merged.

Recommendation caveats

  • The score compares published specifications and a checked offer; it is not a controlled performance test.
  • Scores are comparable only within this category.
  • Published specification inputs can use different test conditions; the retained values are not treated as laboratory-equivalent.
  • No separate third-party source passed the exact-model URL check at refresh.

Owner feedback across the web

No trustworthy exact-model owner-review pool was captured on the source page.

No exact-model review pool passed the current inclusion check.

Independent tests and owner discussion

No separate third-party source passed the exact-model check at this refresh.

No separate editorial, owner-pool or Reddit source passed the exact-model check at the last refresh.
  • No separate editorial, owner-pool or Reddit source was captured for this exact model.
