I purchased this bag because of the low price. I'm an attorney and used this bag once or twice a week.One day I went to court and waited for my case to be called. For 20 minutes I tried to unlock the bag. I knew the combo, and actually tried many different combos with the hope of opening the bag. Several minutes before my court hearing, I asked the marshal for a pocket knife, and sliced open the strap to get to my client's file. The bag was ruined.I called McKlein and they refused to help me. They said the lock was not covered by the warranty. They refused to sew on a new strap, or even supply me with one.I can live with the lower quality leather. This wasn't meant to be a briefcase to hand down to my grandchildren. But I can't live with a faulty lock. Stay away from McKlein.
