No idea of the security aspect as no-one has tried to break into it but it is a very sturdy lock with plenty of space inside to keep any wadge of keys and possible credit cards or wallet even if that is what you want to put in it. Good and solid piece of kt but would advise that it is put in a place that is not obvious for someone to find and chisel off the wall.
A really good size for our purposes, which was for storing a credit card sized car park season ticket for multiple users on an outside wall.
It was a bit stiff to open at first and needed some WD40 to loosen it but otherwise perfect.
Easy to wall mount and it feels really secure on the outside wall.
It was also easy to set the code and the buttons are of a good size so it isn't fiddly to use. There is a pull down cover over the code buttons so it keeps dry and will hopefully keep it safe in all weathers.
Smaller than I thought it was going to be but then I did not take notice of the published dimensions! OK though, easily takes a set of keys and an emergency nifty.
I had a little trouble resetting the combination but got there in the end.
All in great, just check if you want to keep a 9mm Sig in one! Hold an ammo clip ok.
