All yo-yos have passed the manufacturer's quality inspection. Quality standards vary by manufacturer. Basically, products that can be used normally are within product specifications.

Examples of possible initial defects

• if the following symptoms occur immediately after opening, they may be initial defects:
• (Bind models only) The bearing barely rotates even when flicked with a finger.
• Even after dampening vibrations with a finger during play, the yo-yo vibrates so much that its shape appears distorted.
• Parts that should be installed (bearings, pads) are not installed.
• Examples that do not constitute initial defects
• Package damage
• Color differences from expectations
• Bearing noise or bind model return issues that occur after even a few plays
• Yo-yos that arrived properly assembled but cannot be reassembled after disassembly
• Scratches on the inside of the bearing area, paint chips
• Color variations on the yo-yo that are not noticeable from a distance
• Paint chips that are not noticeable from a distance
• Scratches on the yo-yo that are not noticeable from a distance and barely detectable by touch
• Minor rust on bearing surfaces of models that come pre-strung in the package (minor external rust has almost no impact on performance)
