I find it interesting that their device takes a maximum of 2 hours to run through all of the combinations. I lockpicked a Master lock just two days ago (I had forgotten the combo), and by hand it took around 30 min. Master uses certain rules when they create the lock combinations that allow one to reduce the range of possible combos down to a flat 100. Source: http://aaronjasso.com/features/lock9.php
