Thomann Classic TB525 L Trombone

I’m having a Yamaha student model that I don’t want to use in public during performance as I sit next to euphoniums who for some reason are likely to hit my instrument though no ding yet, thankfully. I thought to get a cheaper one also due to high dust at funerals. Slide is not as smooth as the yamaha, but still decent. It has a bit of sound on the slide, hope it will smoothen with time. It’s a bit heavy even for an adult or I’m just used to the smaller yamaha on which I practice regularly. Otherwise good quality for that price.

It has a good sound in every position and all registers.
The material seems to be ok though someone told me these intruments don't have a good oldhood
I usually play big band and folk music as a hobby, nothing professional
I'm happy with it
