One of my pupils has just purchased this instrument and I thought it was excellent value for money. I was particularly impressed by the quality of the slide which was very good. I feel the mouthpiece that the instrument is supplied with is too small and something like a Sonata/Denis Wick 9BS would make the lower register much rounder.
