USA Meyer 6J "Jazz" Alto Sax Metal

This mouthpiece is very good choice for beginners or occasional players who wishes little jazzy and bright sound.

Finally, after years of having this mouthpiece, I can make this review.
For me - a non-professional player who sometimes keeps long breaks - this mouthpiece seems to work pretty well.
The chamber size seems to fit me well during times I play occasionally. Still if I play regularly and lot, the chamber feels little stuffy.
Easy to control, sound is decent jazzy and bright (using Vandoren jazz zz 2.5 reed, Yamaha yas-275).
Usability with the bundled ligature is bad, but with another ligature e.g. Rovner Dark Alto/Tenor Sax Metal 1M everything changes to excellent. Thus highly recommending to get a more decent ligature for this.

Conclusion is that this is a good mouthpiece, I like it, after years I still has it.
I would personally recommend this for e.g. students looking for their first metal mouthpiece.
