Very robust, high quality finish, with inner scrachs to keep you top (blank media and external drive), I have a samsung SE-506 LB in, with some blank media (3 DVD and 2 BR) and its cable USB Y, but with its 240x185x40 mm format (A5 size 4 cm thick) it takes up space in my bag. I walk every day, he already has a few shots on the outer shell (it is made for that anyway), but hey, to conclude, quite big but very sturdy.
