User blog comment:Angel Emfrbl/Append for the Kagamine/@comment-114.79.5.179-20110405145459

True that, but according to Crypton's sales, the Kagamine append is in the TOP 10. It ranked fourth, better than Kaito, better than Miku Append, so, yes. And it's only been four months after their release.

Since the Kagamines are one of the 'early' Vocaloid 2 most producers are more or less familiar with their voices, and they could finally make them sound more human.

If you have six Vocaloids it'd take the producers a LOT of time to get used to ONE voice, after all, six Vocaloids? There are already complaints about Miki being too similar with this, or Kiyoteru being too similar to Kaito.

Well, it's just my opinion.
