Felt I needed to have a few months of playing before I could review this properly.
Since acquiring I've put it through it's paces on Bach B Minor Mass, Haydn Creation and some bits from the Messiah.
It performs well, comparable to the Yamaha on which the model is based. I've only played it in D so cannot comment on Eb, but the tuning in D is true across the register.
It comes with a full set of slides to convert between D and Eb which is easy to change. The tuning slide was a bit loose on arrival, had a habit of pulling away when I opened the water key.. After a slight tweak that now fits fine and doesn't come off.
If you are looking for a solid utility trumpet for the odd messiah then at the price this is an excellent option. You wouldn't know it was a quarter the price of other Eb/D trumpets!
