All are junk as the potmetal castings wear rapidly. From experience in years of home building, Kwikset is the bottom of the heap and for a hope case, I've installed Schlage better grade products. Back to Kwikset... for fun and if you a have a good strong grip on the door knob, you can twist that sucker right off or break it loose. Also, none of them have a long enough deadbolt. During construction, we'd have sets of the cheap brands and after all is completed, painting, etc. new higher quality locksets and doorknobs, etc. would then be installed.

Most residential homes won't have commercial grade steel jamb, steel solid doors and the surrounding framing, studs are wood. Adding a tougher entrance mildly deters but better than going the cheap route. Dumb thieves will attempt and if a little hard on them, will move onto the next but of course, as already mentioned any common dwelling can be broken by a swift kick or crowbar.... or simply break out a window, whatever.

Two ways to look at it. If you have perhaps a second vacation home like a cabin with nominal valuables / furniture, etc. and empty for most of the year, there's no sense in making it super secure. A thief will make more damage to the structure from the break-in. Steel jamb will kink, rip partial out the framing studs, wall board, etc. vs. a cheap wooden jamb. So regardless, with the cheap wood jamb they will enter but with less damage to the door and surrounding structure.

Drifting off the topic a bit but since were talking locks, a few years ago I purchased a $35.00 Master Lock padlock USA made and heavy sheathed cable for my snowmobile. During one of those 200 mile minus 10 degree day rides, the lock as normal was carried in the storage compartment. That night I was ready to lock the sleds together but found the padlock had vibrated apart into pieces! POS!
