"...I won't lose much if it's a piece of crap."
I've played exclusively on this instrument for two years now, my "real" trombones are resting in the corner. The sound is great, it weighs nothing and it's very playable. The bag that it comes with is worthless, though, I'm going to get me a gig bag. The slide keeps getting better (it took quite some time before I could dispense with the oiling and wiping off) and, as can be said about most things in life: "It's good enough for jazz".
