When the Valk3 was originally introduced, the idea of adding magnets to cubes had not been popularized. Since that time, it is a must have for speedcubers. As a result, many were turning to after market versions that had the magnets added to a Valk3.
QiYi has finally introduced a factory made magnetized version of the classic puzzle, updated to allow for perfect placement of the magnets. The result is a great update to an amazing puzzle.
