The Aquarius was the first major release of an offstring yo-yo by YoYoJam. While the OS1 came first, it was not a major release. Aquarius was discontinued at the end of 2002, to be replaced by the Free Agent. Resurrected in the summer of 2004 after problems with the newer models.
Pictured here is a release from January 2005. The second logo design for the Aquarius. Same as the main exhibit, but with black text on the logo. What a difference.
