The mouthpieces are in principle functional. However, the tip opening is very tight, similar to an Otto Link 3-4. In addition, the tip opening is quite short and steep, thus you need either very hard or leaves must be reduced to atmospheric pressure to a minimum when playing. Speech is innately very light and very dynamic. Also playable with bad approach. Unfortunately, on the sheet support even cutter tracks to see. I have retouched with sandpaper and file the path and smoothed, now go quite well. Also the sound has gained significant momentum and focus. Nevertheless, I will retest a mouthpiece before buying the next time.
