I am using this case for my violin after hearing that the materials used to make this case is very heat resistant and very light. It is so light, my 10 year old son can carry it with my violin and music books without problem. I live in a country where it can get very hot as the day goes by and it helps to have a case that is heat resistant to keep my violin in a good condition as I move around. The sheet music pocket is big enough to store 5 normal sized music book. I do not have to carry and extra bags for my music books. The case is very spacious with more than enough space to store everything I need for my violin.
The only disadvantage of this case is that when the sheet music pocket and backpack straps are being used, the case cannot sit properly on the side of the backpack straps. It sits very well with the handle facing up. It is extremely stable and will not fall even if the sheet music pocket is heavy. It is very money well spent. Thomann did a good job in sending it to me. It was well packaged, not damaged in anyway and I got it within 2 days of dispatch.
