## 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.)
