Originally purchased these for my home due to the easy rekeying feature which works very well and is extraordinarily easy to do. Being able to easily rekey all locks within seconds to use the same key without buying a more expensive set with more locks or paying a locksmith to do it is very nice. My only complaint about the original version is that the handle and deadbolt knobs have a bit of a sag to them which appears to be a common complaint. Otherwise, functionally, they're rock solid.For the updated model which this review is for, to an untrained professional such as myself, the inner components appear to be slightly better built, but that could be imagination just looking out for me by trying to convince me that my money was well spent. As for the sag issue I previously mentioned, well, it's no longer an issue with these. The door handle has no play in it and sits perfectly horizontal. The deadbolt knobs also have no play in them, either, and they sit perfectly horizontal when unlocked and vertical when locked. Granted, I didn't get out the level to verify my claims of perfection, but to my hands and naked 15/15 eyes, they look and feel great. And of course the rekey feature also still works just as well as it did on the prior model. Will definitely continue buying this line of entry lock.
