This was my first saxophone, and I bought it before joining any classes.
I was thrilled when I first bought it, and I was blown away by the quality of the sound even though I was just starting to learn the instrument.
The accessories are all very convenient, and the price point is almost unbelievable. The only two things I had to buy were a proper neck strap and a stand.
Later in the year I ended up joining saxophone classes. Upon seeing my Startone SAS-75, my instructor sighed. As time progressed, the reason for the sigh became clearer: the saxophone started to leak in the low notes, the low quality of the build started to show, and just by assembling the neck I would inadvertently cause parts to bend where they shouldn't. A better saxophone, built with better materials, won't give as easily.
I have been advised by my instructor to get a Thomann instrument instead - I'll be getting the TAS-350.
TLDR: Good saxophone for the price, but if you're planning to play for a while go for something better.
