Check the boring details before you keep a find

Most bad saves do not fail because the product is obviously wrong. They fail because the photos are too limited, the size is unclear, the variant changed, or the row never got a real decision.

Product photos show more than one angle. Look for front, side, back, detail, label, hardware, texture, and scale where relevant. One attractive cover image is not enough.
The item type still matches the row. A "jacket" might be an overshirt, a "bag" might be a pouch, and a "sneaker" might be a slide. Move the row before comparing.
Size notes are specific. Write the measurement you need: insole length, waist, chest, shoulder, sleeve, inseam, strap drop, or item dimensions.
The exact variant is clear. Note the color, size, material, version, hardware color, print style, or dial option you meant to compare.
Photos and title agree. If the title says one color but photos show another, or the model image differs from QC photos, keep the row in check instead of keep.
The price has a reason attached. Price alone does not prove value. Add whether it is low, average, high, suspicious, or only useful as a comparison point.
Nearby alternatives were checked. Open the matching product type and compare at least a few similar items before treating one row as final.
The decision is written down. Future you should know whether the row is keep, compare, check, or skip without rediscovering the same problem.

Things worth checking by item type

Different products fail in different ways. Use the item type to decide which details deserve attention first.

Shoes

Check shape, toe box, sole pattern, heel height, stitching, colorway, sizing conversion, insole length, and whether the same pair appears in clearer listings.

Bags

Check dimensions, strap length, interior photos, pocket layout, hardware color, zipper shape, stitching, and whether photos show scale clearly.

Clothing

Check chest, shoulder, sleeve, length, waist, inseam, fabric weight, print placement, wash color, and whether both front and back are shown.

Accessories

Check material finish, clasp, buckle, engraving, lens color, ring sizing, chain length, wallet layout, and small details that are easy to miss in thumbnails.

Watches

Check case size, dial color, marker alignment, bracelet or strap type, clasp, thickness, and whether photos show the actual selected variant.

Electronics

Check compatibility, plug type, model number, included accessories, language or region notes, warranty expectations, and whether the listing details match the photos.

How to decide after the QC pass

Keep the row when the product type is clear, photos are useful, size or dimensions are known, and the variant is obvious. Keep does not mean perfect; it means the row is good enough to compare again.

Compare the row when it looks promising but similar listings may have better photos, clearer sizing, or a more complete product page.

Check the row when one missing detail could change the decision. A check row should always include the exact missing detail.

Skip the row when it has weak photos, unclear item type, no size context, duplicated information, or no reason to survive the shortlist.
