The learning curve was literally about 3 minutes from opening the package to getting locks open in about a second. No idea how I have lived without this!
lt took about 4 hours of trail and arrow to decode the locks opening the old locks was easy.After I decode one the rest were easy.
excelent ! perpect!
Figured I'd try this to see if it worked before I went the bolt cutter route. I'm glad I did.. had the Masterlock 175 open within a few minutes of trying. Works great.
