From what I could find about this instrument it is an intermediate horn, and since the key holes are smaller than most clarinet, this instrument is best for people with smaller fingers.
I play on an Armstrong flute and really enjoy it. I had a friend who played on an Armstrong clarinet, and she had really good tone on it. So, I know that the their flutes are good... I'm not sure if it's the same for their clarinets. I hoped this helped in someway!
