MD,this is an AMSEC, they make one even better than this one.
Depends how mush you want to invest in one.
This one has locking dial so no one can come up and just start playing and spinning it.
The reason is you dial a combination you don't spin it. The combo wheels have parts
on them {called flys} that pick each other up when dialing.If you spin them hard, one
might break off. You'll have a complete lock out! And would have to be drilled open.
