No, more like 15-30 minutes. Enough time for a camera to see what’s up, as I have cameras watching mine and enough time for law enforcement to track vehichle etc just hope home owner doesn’t show up. I ask questions after the fact also my current set up the only way in is through the door so go ahead and saw I’ll munch on pop corn. Sealed it in concrete on all its sides no cutting through that. Their worth it if you have surveillance and the money as insurance will cover everything in certain safes just call your home insurance.
The steel is 11 gauge (1/8th inch thick). So, it shouldn’t take a substantial amount of time. Of course you’ll still have a couple of inches of dry wall to cut through that can be a pain I’d imagine.
