I'm glad you asked. This is the most poorly designed product I have encountered in a long time. When I first looked at it in the local store an associate was showing it to me. The clasp became unattached when we tried to open it and we decided it ws a fluke and so I purchased it. Since I have owned it never once have I been able to unlock the box without the clasp coming undone Replacing it requires squeezing the plastic to hope to get the hinge extrusions to return to the holes in which they fit. I cannot believe that the product designers could be so clueless.
