I bought this a few months ago to replace an older lock on a second home. Install was pretty straightforward, although I had to make a few tweaks - not a big deal (widen the diameter of the hole in the door for the plunger mechanism; also had to invert the inside part of the main lever lock assembly because I installed both smart deadbolt and lever lock - belt and suspenders kind of thing…..it worked, just had to figure it out). So far so good.
