It's big, bigger than the one I have seen at OPEN HOUSE

If you're a person who don't like carry keys around like me, this is a must buy!  I know some people hidding their secret keys under front door's carpet or at their garden's pots; however, they're not safe!  With this lock box, you can hang it anywhere.  Quality is amazing, it's very thick and I don't see the product will break down very soon.  The only tiny issue with this box is the lock number are not easy to move up or down.  However, it's still works.  I will buy another one for the rental house!
