Regardless of the youtube videos that have now educated every criminal with Internet access how exactly to get into people's gun safes. (Thanks jerks) I would say they are a good detergent to your average thief who doesn't carry a grinder with him, keeps your kids safe, and some times helps with insurance if they are stolen or burned in a fire. For what it's worth I've been eye balling that safe at costco and plan on buying one. They used to have a winchester brand the same size that was nice too but I like the door organizer on the brand they carry now. I just wish availability wasn't so hit and miss at my store... they usually order 1 or 2 and they go pretty quick. At 500 lbs I'm not sure where I would put it in my house... Def not something I'd want to move often.
