## What reviewers say

**Yale Assure Lock 2** — Four whitelisted testers (Engadget, TechRadar, Tom's Guide, TechHive) hands-on-tested the Yale Assure Lock 2 (across keypad/touchscreen and Wi-Fi configurations) and all recommend it as a good-looking, reliable smart deadbolt with broad smart-home support. The most common gripes are the dated, buggy Yale Access app (TechRadar, TechHive) and an installation that can need careful attention (TechRadar, Engadget). Tom's Guide separately dinged the lack of fingerprint or tap-to-unlock. Consumer Reports and retailer reviews were excluded. (4 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.)
