I was introduced to these cases when I started scuba diving years ago. They are great for protecting whatever you carry from your everyday briefcase to $8k worth of video equipment. I have never had regular luggage just pelican cases. I always have my cameras and regulator in this case. The only con I have ever found is these cases do attract attention and I have had a couple "LOST" when traveling aboard.
Pros: MADE IN USA! LIFETIME WARRANTY!
Cons: People asking to see it then asking dumb questions. ITS A PELICAN!
