I bought this case for replacement of my childhood Weltklang, which I started to play about 30 years ago. Have not played my alto sax almost for 20 years. Original case was a mess, so I throw it out.
Maybe my son will play saxophone. Weltklang will be good for try.
Thomann case feels pretty durable for protecting saxophone. Could be slightly smaller in dimensions and lighter, but from another perspective- its safer for sure. I like rectangular shape, because it fits better in different stocking places ;)
