FWIW,I have both Kryptos and OnGuards,the Kyptos have a smoother action and aren't as finicky to how carefully you turn the key. I had a couple friends who were locked together spend 30min playing with an OnGuard because a couple of the anti-pick discs had turned. Never had it happen to me,but I'm always real careful with the OnGuards.
