Should I get a wall-mount or a portable hanging lockbox?

Wall-mount boxes (like the Master Lock 5401EC) are harder to walk off with and suit a fixed location such as a home entry or rental unit. Portable hanging-shackle boxes (like the 5400D) attach to a door handle, gate, or railing and are easier to relocate but are also easier to remove. Choose based on whether you need a permanent installation or flexible placement.
