The main issue for me is that the instrument is not really suspended. It is hold tightly indeed, but the material around the instrument is some kind of rigid foam, so it does not filter any vibration or shock: everything is transmitted to the instrument and increases the risk of pegs release, or even the sound post move.
Also the box for the accessories is not practical: to get anything from it, like rosin or a tissue, you have to put the instrument somewhere else, which loses the purpose of the case...
The straps for carrying the case are OK but quite thin and the cussions are from some kind of rubber or plastic which is not very nice for the shoulders if you carry it on thin clothes in summer.
Overall, this case is OK but don't expect to carry it around a lot in public transport or on a bike: the instrument is not very well protected from shocks.
