Let me start this review by saying that I've tried quite a few mouthpieces from other brands : Syos, Jody Jazz, Dave Guardala, Yamaha, Brancher, Drake. None of the other mouthpieces that I've tried have been as easy to play and as responsive as this mouthpiece. I've found that for some people this mouthpiece may be too free-blowing but that's down to personal preference.
The quality of the mouthpiece is really high. The exterior is finished incredibly well. There are no scratches, nicks or other imperfections on my particular mouthpiece. The only thing that i dislike on the hard rubber models is the ligature. I find that the ligature tightening mechanism sticks out a bit too much for my liking and after some time one side of the ligature started being weaker than the other. This may have been caused by me putting some force into it when taking off the mouthpiece but that's the reason why i don't like how much the bottom sticks out.
The mouthpiece has a medium-bright sound and has a great core. But if you need to you can push it to get that extra edge in the sound. This makes it great for playing in big band or pop settings. Overall, a very versatile mouthpiece. If only it wasn't so expensive.
