Helps protect our documents

We have a Smaller one that would not hold all the documents that we had inherited for my relative passing. They have an older safe with a key and combination. We only wanted a key type this fit the bill and since we already had a different one from Sentrysafe we Knew it would work.

Great upgrade

Great upgrade from our last Sentry. Our last, similar sentry safe finally had locking mechanism issues. It was a hand-me-down so we decided to get a new one. All the quality is still there, but we love that we can just close and latch it so we don't need a key to get in every time. When we are going to leave we lock it and ll is secure. Great product and great upgrade.

Safe review for rubber seal improvement.

The safe is great for fire protection but the rubber seal ring around the lid is too thick and lid does not close to lock position. Using the safe without the water seal ring and closes fine.
