P2
Product 2: eufy Video Smart Lock E330
4.8
Reviewers who evaluated event history found it useful for checking clips and seeing who came or went, especially for family awareness.
App
P1
Product 1: Level Lock+ Smart Lock
4.1
The app was praised for features and access sharing, but its setup and firmware-update experience could be uneven.
P2
Product 2: eufy Video Smart Lock E330
4.5
The app was consistently praised as simple, polished, and useful for setup, live view, lock control, access management, and monitoring.
Auto-lock
P1
Product 1: Level Lock+ Smart Lock
3.3
Auto-lock was useful but limited because it relies on timing rather than knowing with certainty that the door is closed.
P2
Product 2: eufy Video Smart Lock E330
4.8
Auto-lock drew strong praise for reliably relocking after a set time and reducing worry about whether the door was left unlocked.
Auto-relock after failed attempts
P1Product 1: Level Lock+ Smart Lock
No score yet
P2
Product 2: eufy Video Smart Lock E330
5.0
The failed-attempt lockout behavior was viewed as a strong security safeguard when someone keeps entering wrong codes or fingerprints.
Battery
P1
Product 1: Level Lock+ Smart Lock
3.4
Battery replacement was praised as elegant and easy, but battery reporting frustrated reviewers because it lacks precise percentage detail.
P2
Product 2: eufy Video Smart Lock E330
3.7
Battery feedback was the most divided area: some reviewers liked the removable rechargeable pack, while others reported short runtime or slow charging.
Build quality and durability

No score yet
P2
Product 2: eufy Video Smart Lock E330
4.4
Camera and doorbell performance was generally strong, with sharp 2K video, good night vision, fast loading, and useful two-way features, though field of view and door placement limited some setups.
Door-sense
P1
Product 1: Level Lock+ Smart Lock
2.1
Reviewers wanted true door-sense behavior; the repeated concern was that the lock cannot tell whether the door is actually closed.
P2
Product 2: eufy Video Smart Lock E330
2.0
Door-sense was weakly supported because a reviewer specifically wanted a sensor to know whether the door was open or closed.
Door compatibility (deadbolt fit)
P1
Product 1: Level Lock+ Smart Lock
3.0
Door fit was the main setup caveat: smooth, well-aligned deadbolts worked best, while tight clearances, older doors, and imperfect alignment caused extra work.
P2
Product 2: eufy Video Smart Lock E330
2.5
Door compatibility was a major caveat because screen doors, storm doors, deep jambs, and awkward door angles could compromise the camera or overall fit.
Existing hardware reuse
P1
Product 1: Level Lock+ Smart Lock
2.7
Because Lock+ replaces the full deadbolt, reviewers noted less reuse of existing keyed hardware and more friction when trying to keep old keys.
P2
Product 2: eufy Video Smart Lock E330
4.5
Existing hardware reuse scored well in the one clear opinionated case, where the lock worked with an existing strike plate and the reviewer called that nice.
Feature additions via updates
P1
Product 1: Level Lock+ Smart Lock
3.4

No score yetFingerprint
P1
Product 1: Level Lock+ Smart Lock
2.0

P2
Product 2: eufy Video Smart Lock E330
4.9
Fingerprint access was one of the strongest areas, repeatedly described as fast, accurate, responsive, convenient, and the preferred unlock method.
Guest Codes and Access
P1
Product 1: Level Lock+ Smart Lock
4.0
Guest access was well liked for passes, cards, and temporary sharing, though several reviewers disliked requiring guests to install the Level app.
P2
Product 2: eufy Video Smart Lock E330
4.8
Guest access was praised when reviewers could give temporary or remote user access without handing over physical keys.
Hub requirement
P1
Product 1: Level Lock+ Smart Lock
2.6
Hub requirements were a recurring drawback, especially the nearby Connect bridge and the need for separate bridging in some ecosystems.
P2
Product 2: eufy Video Smart Lock E330
3.5
Hub requirement was mixed because the lock can work without a HomeBase, but one reviewer disliked needing a separate chime when used alone.
Industrial design

Key override reliability
P1
Product 1: Level Lock+ Smart Lock
4.1
Physical key fallback was treated as a useful backup, especially for battery failure or less tech-oriented household members.
P2
Product 2: eufy Video Smart Lock E330
4.4
Key override reliability scored well because reviewers appreciated the hidden physical key and backup power options for dead-battery situations.
Keypad
P1
Product 1: Level Lock+ Smart Lock
3.5
The optional keypad was considered useful, especially for guests and rentals, but reviewers disliked that it costs extra and is not integrated.
P2
Product 2: eufy Video Smart Lock E330
4.6
The keypad was viewed positively for reliability, passcode flexibility, and backlighting, although one reviewer treated keypad access as less preferred than fingerprint.
Keyway quality
P1
Product 1: Level Lock+ Smart Lock
2.0
Keyway quality drew serious criticism because reviewers felt the cylinder was too easy to pick and not robust enough for the price.
P2
Product 2: eufy Video Smart Lock E330
2.3

Lock/unlock speed

5.0

P1Product 1: Level Lock+ Smart Lock
No score yet
P2
Product 2: eufy Video Smart Lock E330
4.9
Notifications were a clear strength, with reviewers describing alerts as nearly instant, responsive, fast, or consistent.
Physical attack resistance
P1
Product 1: Level Lock+ Smart Lock
4.5
Physical forced-entry strength was praised by one reviewer based on the lock's residential rating and deadbolt strength.
P2Product 2: eufy Video Smart Lock E330
No score yetPick/drill resistance (if rated)
P1
Product 1: Level Lock+ Smart Lock
1.8
Pick resistance was a weak point, with reviewers citing easy picking and available-tool attacks as a meaningful security caveat.
P2Product 2: eufy Video Smart Lock E330
No score yetRemote access
P1
Product 1: Level Lock+ Smart Lock
3.8
Remote access was useful and sometimes reliable, but it depended on bridges, HomeKit hubs, or Wi-Fi Connect rather than direct lock Wi-Fi.
P2
Product 2: eufy Video Smart Lock E330
4.8
Remote access was rated very highly because reviewers liked being able to view, unlock, greet visitors, or control the lock from the app remotely.

Smart-home integration (Alexa, Google, Siri, HomeKit, Matter, Thread)
P1
Product 1: Level Lock+ Smart Lock
4.4
Smart-home integration was strongest for Apple HomeKit and Home Key, while broader ecosystem support was more conditional or dependent on updates.
P2
Product 2: eufy Video Smart Lock E330
4.0
Smart-home integration was mixed-positive: Alexa, Google, Apple Watch, and Eufy ecosystem links were appreciated, but lack of HomeKit hurt one review.
User access management
P1
Product 1: Level Lock+ Smart Lock
4.5
User access management was a strength, with reviewers praising flexible control over household members, guests, cards, and shared access.
P2
Product 2: eufy Video Smart Lock E330
4.5

Value and Price
P1
Product 1: Level Lock+ Smart Lock
2.9

P2
Product 2: eufy Video Smart Lock E330

Wi-Fi
P1
Product 1: Level Lock+ Smart Lock

P2
Product 2: eufy Video Smart Lock E330
4.0
Wi-Fi was mixed-positive: one reviewer saw fast alerts even on weak 2.4GHz Wi-Fi, while another warned experience depends on network strength.
