I really liked the bag when i first saw it. I've been carrying a travel hard-case and it's been pretty tiring. Getting this was such a relief because now my almost daily walk with the saxophone is extremely easy. I can fit everything, and take it all barely feeling the weight. 
The problem is that the handles are constantly loosening up, so i have to pay attention to it, or else, it will get loose and fall of my shoulders. 
 
If the handles locked, it would be a perfect bag. And the fact that it risks dropping the saxophone to the floor, it's a major setback. 
 
Other than this really annoying problem, i like it, as it really helped me.
