Hello, a priori it is a good semi rigid bag that should properly protect in case of slight shock ... It is virtually guaranteed "life" and it is likely taking into account the guarantee and its visual quality is at the rendezvous ... As against this bag does not suit me because my WD Passport Drive 2.5 "tends to float in the illustration while you might think that a disk 2.5" filled the entire interior space, it did nothing. .. Also this bag despite its "small" size is difficult to fit in any pocket and I do not find it suitable to the current ultra portable drives ... As long as you buy a tiny disk and put it in a protective case so that the whole is as compact as "possible" ...
