Amazon Due Diligence
Report for YY Wireless

Report Date November 30, 2025
Recommendation
Caution
Overall Summary
Suspicious
Why we think so

Quick verdict: the listing is for a legitimate Amazon product (ASIN B0CMZBXYWX) sold by a high-volume third‑party called “YY Wireless,” but the seller has a mixed track record across platforms. The Amazon product page looks complete (images, specs, price $558.90 for a renewed iPhone 15 Pro), and the seller has thousands of Amazon reviews and many active listings. However, independent sources and customer complaints (BBB / Trustpilot) report recurring refund, return, and misrepresentation issues for YY Wireless / Bayshine Trading, so treat large refurbished phone purchases with caution. 🛡️

Risk Insights

⚠️

External complaints vs Amazon profile

On-Amazon metrics look strong (many listings and positive rolling ratings), but independent complaints (BBB / Trustpilot) describe serious, recurring issues around returns and misrepresentations.
This mismatch increases the chance of post-purchase disputes even when the listing appears normal.
Verify IMEI/serial and prefer FBA/Amazon‑Renewed or a card with strong chargeback protections for expensive refurbished phones.
🧭

Large catalog, mixed risk

Seller has hundreds of refurbished listings which can indicate scale and supply access.
Scale can mean good inventory but also more operational errors and higher complaint volume.
For high-value items, treat individual listings on their own merits and request device identifiers before purchase.

Contradictory Signals

Large-scale Amazon sellers can maintain strong platform metrics while still generating many off-platform complaints; platform ratings alone are insufficient for trust with refurbished high-value devices.

Signal A: Strong on-platform metrics (thousands of Amazon reviews, active sales)

Signal B: Off-platform complaints alleging refunds/returns problems and misrepresented items

Red Flags & Warnings

  • Consistent external complaints about returns/refunds and misrepresented device conditions associated with YY Wireless / Bayshine Trading (BBB and Trustpilot summaries).
  • High-volume seller with many refurbished listings increases operational/quality control risk for expensive items like smartphones.
  • Product is refurbished/renewed; refurbished phones carry higher counterfeit / functional-risk unless serial/IMEI is verified with Apple.

🔎 Detailed Checks & Analysis

ASIN & Listing Integrity

Score: 85/100
Passed

"The product page includes multiple high-resolution images, full spec sheet, variant ASINs, and shows recent sales activity — all signs of an actively maintained Amazon listing."

Reason: Product ASIN B0CMZBXYWX contains complete metadata, images, variant ASINs, and specs consistent with an iPhone 15 Pro renewed listing.

Seller Existence & Identity

Score: 70/100
Passed

"Seller metadata includes a business name and physical address; that increases traceability, but a public address does not guarantee good post-sale behavior."

Reason: YY Wireless is a visible Amazon seller with an Amazon seller profile, logo, and business name (Bayshine trading inc) and a US address.

Seller Reputation (on-platform)

Score: 65/100
Passed

"On-Amazon metrics are favorable (thousands of reviews and positive rolling averages), which suggests scale and many satisfied buyers on-platform — but platform metrics can be noisy for large sellers."

Reason: Seller shows large lifetime review counts and positive average ratings on Amazon metrics.

External Reputation (off-platform complaints)

Score: 28/100
Failed

"Independent complaint sites report patterns: refunds not issued after returns, devices sold as 'unlocked' but carrier-locked, and poor refurbishment quality — these are material issues for refurbished phones."

Reason: Multiple independent complaint summaries (BBB, Trustpilot) document recurring return/refund disputes and product misrepresentation under the same seller names.

Pricing & Market Comparison

Score: 75/100
Passed

"Price is discounted but comparable to other refurbished channels; extremely low prices would be a stronger scam indicator."

Reason: Listing price (~$558.90) is within the range of other legitimate refurbished sellers (Back Market, Best Buy references), not an extreme outlier.

Fulfillment & Return Protections

Score: 48/100
Failed

"FBM fulfillment puts more responsibility on the seller for returns; if the seller has a history of return disputes, FBM increases buyer risk. Prefer FBA / Amazon Renewed for high-value refurbished purchases."

Reason: Seller indicates 'fulfilled by YY Wireless' (FBM) rather than FBA in the snapshot, which can reduce Amazon-managed return protections depending on the listing.

Image / Counterfeit Signal

Score: 80/100
Passed

"No immediate image-reuse flag from a single lens check, but image checks are not conclusive; verifying serial/IMEI with Apple is the definitive test for counterfeits."

Reason: Product imagery and variants are consistent with genuine Apple iPhone 15 Pro photos; no obvious reverse-image misuse from the basic lens result.

Your Next Steps

  • 1
    Before buying, confirm the exact seller on the Amazon checkout page (check 'Sold by' and 'Fulfilled by').
  • 2
    If you proceed, pay with a card that allows chargebacks and keep all shipping/return tracking numbers and packaging photos.
  • 3
    Ask the seller (via Amazon messages) for the device serial number / IMEI and verify it on Apple's Check Coverage page before accepting the device.
  • 4
    Prefer FBA-fulfilled items or purchases from Amazon Renewed / Apple official refurbished channels for higher return protections.
  • 5
    If you see any post-sale dispute (refund/return denial), escalate to Amazon A-to-z Guarantee and preserve evidence (photos, timestamps, return label).
