For such a price, this is an excellent choice, especially as the basic organizer for your 19" equipment. Of course, if you are constantly on the road on tours, perhaps you should take something stronger, but for infrequent trips to gigs and work in the studio/home, it’s perfect.
I use the 4U version of the case where all the slots are equipped (one slot takes up the spacer), and the equipment inside the case is about 30 lbs in weight and the case holds this weight perfectly. It seems that the plastic has excessive flexibility, but I don’t see this as a problem.
