Bests & Worsts Reviews from Amazon

We invest in real estate and use lock boxes all of the time. This looked like a good buy. It even worked real well for a while. Then one day it just would not open for my property manager (PM). She tried like crazy to get it open, then it finally popped open. After that it would open for ANY combination. One down... Now I'm trying to sell my house so I put another one of these on my own house. I used this box every day to gain access to my house as it was MY key in the box. Well this one died too. I had a termite inspector coming to the house that day and he was not able to get in either. I had to climb through a window to gain entry to my house. I then removed the door knob so I could take this thing to my work bench where I was able to break into it. That is another bad point about this lock. I hit it no more than 20 times hard with a normal hammer on the hinge at the bottom and it just opened right up. So all around this thing is just a hunk of junk. I would avoid it.
