Pros
Sort
-
Palm vein recognition was the clearest strength, repeatedly described as fast, reliable, convenient, and easier than fingerprints, with minor caveats about angle and unlock-only use.
-
Motion and doorbell notifications were mostly praised for speed and accuracy, with one reviewer noting a small delay.
-
The dual-battery design was one of the most praised practical features, although heavy camera use made one reviewer doubt the advertised runtime.
-
Camera and doorbell performance was mixed-positive: daytime video, field of view, and the indoor screen drew praise, while low-light video, audio, and doorbell-button expectations were caveats.
-
Reviewers generally found setup straightforward and app-guided, though one pre-release unit caused connection and install friction.
-
Auto-lock was viewed as a meaningful convenience and peace-of-mind feature, especially for families that forget to lock up.
-
The keypad was generally praised as responsive, visible, and easy to use, with scramble-code support helping privacy.
-
Locking reliability was consistently strong in the reviews that tested repeated lock/unlock behavior and routines.
-
The Eufy app was considered capable and feature-rich, with useful controls and setup help, but one reviewer found it sprawling.
-
Wi-Fi performance was positive overall, with quick setup, steady connectivity, and claimed responsiveness from Wi-Fi 6 support.
-
Build quality drew strong praise, with reviewers describing the lock as robust, durable, and safe-like despite its size.
-
Industrial design was seen as modern and premium, though several reviewers noted that the lock is large or visually high-tech.
-
Voice control worked quickly where tested, especially through Alexa, Siri, or Google lock commands.
-
Value was mixed: reviewers repeatedly called it expensive, but some felt the all-in-one lock, camera, and doorbell package justified the premium.
-
Facial recognition was praised when paired with HomeBase, but reviewers treated it as an add-on rather than a built-in core feature.
-
Pick resistance was praised in reviews that discussed the encrypted cylinder or difficulty of picking the lock.
-
User access management was praised for making family access easy and supporting different time slots.
-
Physical attack resistance had limited but positive evidence, with reviewers pointing to solid construction and tough security design.
-
Reviewers treated the physical key override as a useful fallback for emergencies or users who prefer non-smart access.
-
Smart-home integration was the most split area: basic Matter, Alexa, Google, and HomeKit control worked, but advanced lock, camera, and palm features often stayed inside Eufy.
-
Lock/unlock responsiveness was excellent in testing, especially with voice commands.
-
Touchscreen/keypad usability was supported by positive comments about responsiveness and backlighting.
-
The motorized lock button was praised as making operation easier, particularly for users with limited hand comfort.
-
Remote access had limited evidence but was described as quick and reliable.
-
Security encryption evidence was limited but positive, centered on the encrypted lock cylinder adding protection.
-
Finish durability was only lightly covered, but one reviewer said the black metal casing still looked good after use.
-
Weather resistance received limited but positive support tied to the lock’s durable construction for harsh conditions.
-
Wrong-try lockout was viewed positively as a useful safeguard against repeated bad attempts.
-
Door-sense received qualified praise because it can infer door state without a separate sensor, though with some edge-case caveats.
Cons
Sort
-
Door fit/usefulness is context-dependent: glass, windowed, screen, or storm doors can reduce the value of the camera and interior display.
-
HomeBase dependence was a downside when reviewers wanted facial recognition or the most advanced alerts.
-
The hidden keyway cover was the weakest physical detail, with one reviewer finding it hard to reseat securely.
