Review methodology

Review Methodology

Every review starts with an order. We use a dedicated Kakobuy account and a Yupoo album tracker to log each purchase. We record the date ordered, agent response time, QC photos, shipping method, and delivery date.

When the package arrives, we open it on camera. We check packaging, tags, and any included accessories. For apparel, we measure chest, shoulder, sleeve, and length against the seller's size chart. We also do a wear test over several days. For accessories, we check materials, hardware, and stitching. For electronics, we test functionality and battery life.

We compare each product against a retail authentic when possible. We note discrepancies in materials, construction, and branding. We then assign a score from 1 to 5, with 5 being excellent.

We publish full testing notes, photos, and agent timing in each review.

Comparison scope

Preserve the ordered variant and the size chart available at purchase. Compare warehouse and arrival measurements using stated landmarks. Describe seams, hardware and defects without inferring untested composition. Wear or washing claims need the actual duration and care conditions. Distinguish visible inspection from laboratory testing and authentication; one item's quality cannot establish the reliability of every catalog entry.

The review identifies the sample, dates, conditions and any steps omitted. A hands-on claim requires documented inspection or use; desk research is labelled. Scoring uses the complete 1-to-5 scale with the criteria and evidence explained, including unfavorable findings and missing information.
