I bought this as I am planning to join more ensembles at university - I play low brass (valved) and wanted to play in more stuff.
It arrived well protected in near perfect condition with a few tiny imperfections (which would likely be unnoticable from a small distance).
From playing it for a couple of hours, it has a great sound. Very bright, but I was expecting that from a small bore, and thus it's perfect for the job in jazz but not as fitting for orchestras and concert bands as large bores.
The slide does make a fair bit of noise (including after a first bath) but hopefuly that will go away in a few days/weeks of breaking in (or with a little more lubrication). Even so, it's certainly smooth enough to play comfortably.
No problems with resistance in the air flow, and the high register plays softly surprisingly well compared with the lower register, and doesn't lose any of the lyricism. And of course, it's a trombone, it's loud/brassy when you loosen the tap!
All in all (TL;DR), it's exactly what I was expecting for the price (if not more), and I would highly recommend it!
