## What reviewers say

**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.)

**Ultraloq U-Bolt Pro WiFi** — Two hands-on testers reviewed this exact model: TechHive (Christopher Null) and Reviewed/USA Today (Rick Broida). Both praise the fingerprint reader, easy installation, multiple entry methods, and built-in Wi-Fi that needs no separate bridge. Both flag the strict 2.4GHz-only Wi-Fi with no dual-band support. They split on Wi-Fi setup reliability: TechHive called the built-in Wi-Fi 'half-baked' after it refused to join a mesh network, while Reviewed's app connected in seconds. (2 sourced reviews.)
