What reviewers say
Sourced tester consensus for each — the "what people who used it think" layer, not just specs.
August Wi-Fi Smart Lock (4th Gen)
Two whitelisted hands-on reviews (Engadget, Tom's Guide) cover this exact 4th-gen August Wi-Fi Smart Lock; both recommend it for an easy, tool-light install, a smaller hidden design, built-in Wi-Fi and broad smart-home support. Neither published lab benchmarks, so there are no measured numbers. Main gripes: unreliable Android auto-unlock (Engadget) and a keypad sold separately for $59.99 (Tom's Guide). (2 sourced reviews.)
Praised: Fast, tool-light install that keeps the original keyway and physical keys; Smaller, discreet design that hides on the inside of the door; Wi-Fi built in, so no separate bridge is needed for remote lock/unlock.
Flagged: Auto-unlock is finicky and unreliable, especially on Android; Keypad is not included and costs extra ($59.99); Dropped Z-Wave, so power users lose offline local control.
Level Lock Pro
Only one whitelisted tester, PCWorld/TechHive, published a hands-on review of this exact 2025 Matter-over-Thread Level Lock Pro; it calls it the best and most attractive smart lock you can buy and recommends it without reservation. No lab measurements are reported. (1 sourced review.)
Praised: Invisible design that looks like an ordinary deadbolt, not a smart lock; Supremely easy, fast installation and setup; Matter-over-Thread lets it work across multiple smart home ecosystems (Apple Home, Alexa, SmartThings) simultaneously.
Flagged: High price at $349; Numeric keypad is an added-cost option ($79); No biometric access (no fingerprint or palm-vein reader).
