Our take
If you're deep in the Apple ecosystem, the U100 is the obvious choice — Apple Home Key is genuinely magic, and no other lock delivers it this cheaply.
If you only read one recommendation, it's this: the Yale Assure 2 is the community consensus pick, full stop. It's reliable, ecosystem-agnostic, and you won't regret it.
