The design is very well thought out. I really like the fact that you can fit in a large shoulder rest which would not fit in the compartment you find in most violin cases. Being carbon fibre it is very strong and light, and the shoulder straps are comfortable.
My only concerns initially were how secure the velcro straps holding the shoulder rest might be, also that there seemed to be less padding around the violin than more conventional cases. However, I have had no problems with these issues, so I give it 5 stars without hesitation.
