After buying the first box I was so excited that I immediately ordered 2. In three different colors. Thus, a faster allocation of the contents is possible. In one case there is space for two 2.5 "" HDs and the associated cables. For me, even 5-6 USB sticks fit with pure. The casing is very stable. Of course, if I want to get them broken, then I take a hammer or hit with anything a fact. Also I think that one should not dance to it. But very robust for normal use. The additional carabiner is also very useful. I would buy this part at any time.
