Query: Low Quality

The "3600 Series" boxes included have fixed dividers, unlike the actual 3600 box sold separately. The case is very flimsy and arrived completely bent out of shape by the plastic shipping strap. The boxes do not snap into the case and fall right out. The cases are "stackable," but do not lock together. I cannot recommend this product. I intend to return the two I bought.
