I like Protec instrument cases - they are always nicely made, good value and look very smart. This was no exception, with strong positive zips. It is a neat and lightweight case giving good protection. I bought the backpack clip-on straps and that is where the problem arises. Because it attaches on the rim of the case, it ends up contorting your neck and back. It was really uncomfortable for my daughter to use and I found it horrible myself when I had to carry it for her one time. So, it's a great case if you DON'T use the back pack straps but absolutely terrible with that attachment. I can't believe they didn't try it first - if they had attached it to the body part of the case (like every other manufacturrer does) it would have worked fine and, like other cases, the bell could sit behind your head with the case itself flat against your back, rather than trying to bend your out of shape.
