If you own a DDJ-SX, you absolutely need to buy this case. It is the best protection for my $1000 investment I could find. It is made to fit, has extra padding for customization, and the shelf slides back enough to give access to all of the effects knobs without risking your laptop falling off the back of it. The latches are superb, and there is even a protective foam block to keep the shelf from sliding while transporting. Also, with the space for cables on the back end of the case, I don't need to bring extra bags for power strips, interconnects, etc.
