Yeah as long as we don't have unrealistic expectations from our $30 deadbolts and our $5 combo locks it's fine. But people sometimes buy the cheap thing and expect it to perform as well as a really expensive thing.
That's usually with skills that few have the time to acquire. But I also saw on LPL where he tested a cheap Chinese lock, where the "hardened steel" had a visible groove after just a few strokes of a file, and you could use pliers to rip off the plastic cover around the keyhole, after which all the little parts of the lock mechanism came tumbling out...
