I play on a Pomarico 3. This was an order on request of a friend who does not have an account by Thomann.
The mouthpiece is of good quality (as usual with Pomarico), sound is good. There was a clear difference in response for me between the Pomarico 2 and 3. More than I expected.
My friend likes the mouthpiece a lot, but found it was more difficult for him to play than his previous mouthpiece (a standard Yamaha 5C).
