The storage capacity is large enough for our needs without being oversized. Have had a SentrySafe at each of our previous homes. This model has both fire/water where our previous models were fire only.  This is the first model purchased with the digital combination which is some what simpler than the previous dial combination. We especially looked for a safe that had both key and combination locking which our previous models of safe had. The combination of previous ownership, capacity, dual locking, and price made this the optimal solution for our document storage needs.
