This mouthpiece is amazing, enough said, I have been playing clarinet for 3 years and in my third year my band teacher gave this mouth piece for me to try out, I immediatly fell in love because it creates a fuller sound, the only snag is I hate vandoren reeds (if you want some reeds that are easier to play on go for mitchel lurie, just saying) and when you use any other reed other then vandoren, spit seeps out the sides of the reed all over your face while your playing. This isn't a terrible thing though and i thought it was just me until my friend got the mouthpeice and she had the same problem, so if you want a fuller sound and no spit, get use to vandoren reeds, if you don't mind a little spit then i totally suggest mitchel lurie (cheeper and fuller sound and easier to play on) other then the spit, this mouthpeice really helped me win a lot of compitions too :) amazing mouthpiece
