I bought this case because of how much it (doesn't) weight.
To that end, you really do get the bare minimum. There's room inside for the sax, a neck and a mouthpiece. If you want to carry reeds or a neck strap I recommend you get one of those in-bell storage pouches.
The backpack straps are adequate and the clips seem to be sturdy.
4 stars for stability because it's one of those cases that falls over backwards when you take the sax out.
