We couldn't have said it better! Here is a review of the sister model 989GL from www.saxophoneadvice.com:
This lovely step up model from Jupiter offers excellent value for the advancing student. While not quite a professional instrument, this is a great model for those students who have been playing a student model Jupiter for some years, as they will be used to the feel and response. In addition, it is a fantastic choice for the beginner and will take them through to a higher level than they might otherwise achieve with a student instrument.
The ergonomic key and body design, a specialty of Jupiter, is comfortable to play and offers easy and intuitive response which is a fantastic benefit. The 989GL looks lovely too, with a pro-style badge and inlaid octave key. In addition, the hand hammered brass neck provides excellent projection and tonal centering.
Overall a really strong, well priced intermediate sax and a good choice for beginning or advancing players.
