well, I wasn't only disappointed at the price which, in my view, puts the horn in a completely different market that it was originally envisaged by the maker.
I was disappointed at the actual quality of what I was delivered and I would have been disappointed about that regardless of the price paid.
My horn had a neck octave key operating erratically. Two coil springs of the palm keys jumped out as I attempted to operate them (because the glue had crystallised at the base of the spring, where a black plastic disk is supposed to make contact with the body of the horn). Several other keys were not closing well one wasn't doing so on account of a rod that wasn't turning as it was supposed to because it wasn't straight.
I was then told to watch out because the fixed needle springs (again if anyone would ever need replacing one I would be most interested in hearing how they would do that because they are sort of melted in the body of the sax!) had been coated with vegetable oil which was incompatible with the Bayer plastic.
The left hand table (which has been redesigned afterward) was so bendy because the plastic had not structural resistance.
Frankly speaking, I saw no reason to be happy about it so I returned it and obtained a full refund.
I have then , at Frankfurt, seen their improved version they were indeed better but I had lost trust in the project altogether.
