This case contains three Quest Edge-family noise dosimeters, a confirmed five-bay EdgeDock-5, and a QC-10/QC-20-family acoustic calibrator. EG4 versus EG5 identity, current calibration, battery health, dock communication, and the auction bid are not preserved, leaving a $400 blind ceiling and REVIEW recommendation.
Stale-data warning
Analysis snapshot · Close time not preserved — observed September 1, 2026. This is an immutable observation, not a live feed. The scheduled close was not preserved in the available evidence. Price, status, terms, and close time may have changed. Check the source auction before bidding.
The auction bid ceiling supported by this analysis, if one is defensible; see costs below for buyer-premium treatment.
Why this decision
REVIEW: a $400 blind ceiling is reproducible from the $1,500 visual-only whole-kit model, but the unresolved exact variant, calibration, battery and dock function, and missing observed auction price prevent a BUY or SKIP decision.

The September 1, 2026 research record does not preserve a reliable immutable bid or bidder count. The page therefore uses an observed snapshot rather than inventing an auction result.
A coherent measurement kit can have important hidden value and risk in exact model, charging/data workflow, battery, and calibration evidence.

The original CALIBRATED state exceeded the preserved photo evidence. The page's dated narrative already says neither the sticker nor the envelope establishes current calibration.

Not Recorded
No structured comparable-evidence metadata was preserved for this dated snapshot. Public auditability is limited; the numeric resale snapshot cannot be independently audited from comparable records on this page.
Legacy evidence counts were not preserved. Unknown is not reported as zero.
Requires Verification
The scenarios show potentially workable economics, but the stated verification gate must be resolved before bidding responsibly.
The $400 ceiling reserves for handling, representative checks, battery/accessory risk, selling friction, profit, and uncertainty. It does not assume EG5 identity or current calibration.
| Transaction / operating cost | Amount | Basis |
|---|---|---|
| Selling Fees | $225 | LotCaliper assumption: 15% of conservative gross resale. |
| Shipping | $75 | LotCaliper pickup, parcel shipping, and handling reserve. |
| Testing Repair Reserve | $100 | LotCaliper reserve for charging, cleaning, and representative functional/DMS checks. |
| Other | $200 | LotCaliper battery, microphone, and missing-accessory reserve. |
| Risk Buffer | $100 | Variant, calibration, battery, dock, and auction-state uncertainty reserve. |
Profit floor: $400
ROI floor: $506
Binding: Profit floor
This is a reseller ceiling, not a prediction of the auction's closing price. Any buyer premium or other unquoted acquisition charge must be deducted before bidding.
Historical five-unit EG5 kit evidence makes EG5 plausible, but no readable model label or approval marking establishes it. The three photographed units are not treated as an incomplete five-pack merely because the dock has five positions.
A calibration sticker and case paperwork are useful historical clues, not current calibration. The blind model requires separate verification of each battery, microphone, dock bay, and software communication path.
Snapshot decision
REVIEWREVIEW: a $400 blind ceiling is reproducible from the $1,500 visual-only whole-kit model, but the unresolved exact variant, calibration, battery and dock function, and missing observed auction price prevent a BUY or SKIP decision.
Market support assesses how well the available evidence supports the resale assumption. Exact third-party marketplace records may be omitted when source-use rights are unclear. Each dimension uses the published methodology rubric; a confidence label measures the strength and boundedness of its evidence, not the likelihood of a profitable outcome.
High · Model Variant Unresolved
EG5 and EG4 have materially different capability and market context.
High · Dock Communication Unverified
The dock is decision-relevant to practical charging and data workflow.
High · Calibration Unverified
No current serial-matched calibration evidence is preserved.
