I bought this case as an upgrade from the free one that came with my Thomann Flügelhorn and it solves all the problems I had with that one:
- plenty of space for large music notes
- separate organiser space for the bits and bobs you always need to take along
- lightweight
- sturdy rucksack straps
I've given it 4 out of 5 instead of 5 due a couple of things I will need to hack by myself:
- it's black and hard to see at night when walking or cycling, it needs reflector strips
- some way to externally carry a standard drinking bottle would be great, like those mesh pockets in many rucksacks
Add those, and it would be a perfect case. As it is, it's really good and I highly recommend it.
