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)

Description

YoYoJam - Diamond Back

The Diamond Back is the new signature model for 2008 1A US national champion, Eric Koloski.

This is Eric Koloski's second signature model, with a beautiful mix of aluminum body and nickel-bronze weight. An update from his previous signature model, the New Breed, Diamond Back has a similar size, but with an even lower edge. The low edge creates increased stability, and the slightly inverse rounded body shape helps keep friction to a minimum during play. The Diamond Back plays incredibly smooth for a very long time.

True to its name, the Diamond Back has YoYoJam's new proprietary diamond pattern design etched on both the side and inside edge of the yo-yo for a feel similar to the Next Level.
