The safe operates just fine, and both my wife and I have been able to open the safe easily with the manual combination lock. But the plastic concrete anchors include with your kit did not fit in the specified concrete holes; going in about ½ way and then collapsing when lightly tapped with a rubber hammer. Needed to purchase metal anchors at the hardware store and slightly increase the diameter of the holes in the concrete; which then allowed the proper installation of the lag bolts.
