App
P1
Product 1: eufy Video Smart Lock S330
4.6
The app was usually described as smooth, easy, useful, or user-friendly across reviews.
P2
Product 2: Schlage Sense Pro
4.6
The Schlage app offers useful controls for modes, alarms, access, and remote operation. It was stable after connection, though setup and Apple Home pairing were frustrating for some reviewers.
Auto-lock
P1
Product 1: eufy Video Smart Lock S330
4.3
Auto-lock was valued for peace of mind, though one reviewer cautioned against using timed auto-lock without reliable door-position awareness.
P2
Product 2: Schlage Sense Pro
4.9
Auto-lock worked reliably and can be configured in either Apple Home or the Schlage app. Reviewers valued not having to remember to secure the door manually.
Battery
P1
Product 1: eufy Video Smart Lock S330
4.4
Battery life was generally praised as long-lasting, though full charging can take several hours.
P2
Product 2: Schlage Sense Pro
4.2
Four AA batteries are easy to replace, Thread can extend runtime, and USB-C emergency power is a strong fallback. Some reviewers still preferred a rechargeable battery pack over replacing cells.
Build quality and durability
P1
Product 1: eufy Video Smart Lock S330
4.8
Reviewers consistently praised the heavy, metal-feeling construction and durable build.
P2
Product 2: Schlage Sense Pro
4.9
Reviewers consistently praise the all-metal construction, premium feel, and careful engineering. Even the most critical reviewer described it as a well-built, high-quality lock.
Camera and doorbell performance
P1
Product 1: eufy Video Smart Lock S330
4.3
Camera and doorbell performance was generally strong, especially video clarity, but motion timing, distance, and visitor button clarity were recurring caveats.
P2Product 2: Schlage Sense Pro
No score yetDoor-sense
P1
Product 1: eufy Video Smart Lock S330
3.0
Door-sense evidence was mixed: departure detection was useful, but one reviewer criticized the lock for not knowing whether the door was open.
P2
Product 2: Schlage Sense Pro
1.5
The lock lacks a door-sense feature that reports whether the door is open or closed. This is a clear disadvantage beside the Aqara U400.
Door compatibility (deadbolt fit)
P1
Product 1: eufy Video Smart Lock S330
2.7
Door fit was context-dependent: some installations worked smoothly, while shallow strike plates, alignment, and size constraints caused problems.
P2
Product 2: Schlage Sense Pro
5.0
The flattened deadbolt fit one previously troublesome door without adjustment and locked cleanly. Fit feedback is positive but comes from limited direct testing.
Feature additions via updates
P1
Product 1: eufy Video Smart Lock S330
4.5
A post-review feature addition impressed one long-term reviewer by making live-view unlocking more convenient.
P2
Product 2: Schlage Sense Pro
3.3
Aliro promises broader Samsung and Google wallet support, but reviewers repeatedly noted that these benefits were not fully available at launch. The future roadmap is encouraging but should not be treated as a current feature.
Fingerprint
P1
Product 1: eufy Video Smart Lock S330
4.4
Fingerprint performance was strongly positive in most reviews, but one reviewer had repeated failed reads.
P2
Product 2: Schlage Sense Pro
2.3
There is no fingerprint reader. Reviewers who regularly enter without a phone considered that a meaningful omission, while others accepted it in exchange for the smaller design.
Guest Codes and Access
P1
Product 1: eufy Video Smart Lock S330
5.0
Guest access was a standout use case, with reviewers liking temporary access, contractor use, and removable access.
P2
Product 2: Schlage Sense Pro
4.9
Up to 250 codes support family, guests, contractors, and other visitors without sharing one credential. Reviewers found guest access flexible and practical.
Hub requirement
P1
Product 1: eufy Video Smart Lock S330
4.3
The required bridge/chime was viewed positively when it improved chime, storage, or camera-feed experience.
P2
Product 2: Schlage Sense Pro
2.8
Basic Wi-Fi control does not require a hub, but Apple Home Key, UWB, and advanced Matter features need a compatible home hub. That adds cost and complexity for households without one.
Industrial design
P1
Product 1: eufy Video Smart Lock S330
4.0
Design was generally liked for its sleek or elegant look, though its large size stood out as a drawback.
P2
Product 2: Schlage Sense Pro
4.9
The slim, all-metal exterior is one of the strongest points, with a concealed keypad and discreet futuristic styling. Reviewers consistently preferred its compact look to bulkier UWB competitors.
Installation and Setup
P1
Product 1: eufy Video Smart Lock S330
4.2
Installation was often described as easy or manageable, but door fit and alignment created trouble for some reviewers.
P2
Product 2: Schlage Sense Pro
3.9
Physical installation is usually quick and straightforward, but software setup is inconsistent. Several reviewers paired it smoothly, while others needed repeated resets, Thread troubleshooting, or even a replacement unit.
Jam detection
P1
Product 1: eufy Video Smart Lock S330
2.0
One reviewer found jam reporting annoying because a calibration issue made the app keep showing the lock as jammed.
P2
Product 2: Schlage Sense Pro
5.0
The deadbolt operates smoothly and cleanly without jamming, even on an older door where other locks may bind.
Keypad
P1
Product 1: eufy Video Smart Lock S330
4.3
Keypad and touchpad feedback was mostly positive, though one reviewer had wake-up/tap responsiveness issues.
P2
Product 2: Schlage Sense Pro
4.2
The hidden keypad is fast, attractive, and useful for guests or phone-free entry. One defective unit failed to illuminate frequently, but its replacement worked reliably.
Lock/unlock speed
P1
Product 1: eufy Video Smart Lock S330
5.0
When working well, unlocking was described as instant or very fast, especially through fingerprint recognition.
P2
Product 2: Schlage Sense Pro
4.9
Unlocking is generally exceptionally fast through UWB, Home Key, keypad, and app control. Multiple reviewers said the door was ready by the time they reached the handle.
Locking motor
P1
Product 1: eufy Video Smart Lock S330
3.5
Motor feedback was split: one long-term reviewer found it solid, while another warned that small alignment resistance could stop locking.
P2
Product 2: Schlage Sense Pro
5.0
The motor moved the deadbolt smoothly and cleanly in an older door. Direct motor feedback is limited but strongly positive.
Locking reliability
P1
Product 1: eufy Video Smart Lock S330
4.2
Reliability was mixed, ranging from flawless and better-than-prior locks to failures when alignment or one-touch locking was imperfect.
P2
Product 2: Schlage Sense Pro
4.3
Most reviewers found the lock fast, stable, and dependable after setup, including flawless daily UWB use in some homes. One reviewer experienced severe approach-unlock failures, and another needed a replacement unit before reliability improved.
Notifications
P1
Product 1: eufy Video Smart Lock S330
4.0
Notifications were mostly praised as quick and useful, but some reviewers reported missed or delayed motion events.
P2
Product 2: Schlage Sense Pro
4.7
The lock can report manual lock activity, low battery, and alarm events. Reviewers appreciated the broad status coverage and visible low-battery warnings.
On-device display
P1Product 1: eufy Video Smart Lock S330
No score yet
P2
Product 2: Schlage Sense Pro
4.3
The keypad, light bar, and warnings appear only when needed, preserving the minimalist face. This looks polished, though the hidden controls can be less discoverable.
Physical attack resistance
P1
Product 1: eufy Video Smart Lock S330
4.5
Physical security impressions were positive, centered on wanting a sturdier alternative to flimsy plastic doorbells.
P2
Product 2: Schlage Sense Pro
4.7
The all-metal build, higher BHMA rating, and removal of the pickable key cylinder inspired confidence. Reviewers generally viewed the physical security design as a strength.
Pick/drill resistance (if rated)
P1Product 1: eufy Video Smart Lock S330
No score yet
P2
Product 2: Schlage Sense Pro
5.0
The keyless exterior removes the traditional cylinder targeted by picking and bumping, although drill resistance was not tested.
Remote access
P1
Product 1: eufy Video Smart Lock S330
5.0
Remote access was a clear strength, with reviewers valuing lock control from the app while away.
P2
Product 2: Schlage Sense Pro
4.7
Remote locking, unlocking, and digital visitor access were considered highly useful. Built-in Wi-Fi allows these functions without a separate lock-specific bridge.
Security features (encryption)
P1
Product 1: eufy Video Smart Lock S330
3.5
Security/encryption evidence was limited but noted an encryption message before streaming, alongside privacy caution.
P2
Product 2: Schlage Sense Pro
5.0
UWB uses a direct device handshake with protections against eavesdropping, tampering, and relay attacks. The technical security design received strong marks.
Smart-home integration (Alexa, Google, Siri, HomeKit, Matter, Thread)
P1
Product 1: eufy Video Smart Lock S330
3.0
Smart-home integration was mixed because Alexa/Google support was useful, but reviewers noted the lack of Apple HomeKit, IFTTT, or Matter.
P2
Product 2: Schlage Sense Pro
4.0
Apple Home, Home Key, Matter over Thread, and built-in Wi-Fi create a strong integration package for iPhone households. Android and cross-wallet support depended on later Aliro updates during the review period.
Touchscreen
P1
Product 1: eufy Video Smart Lock S330
3.8
Touchscreen feedback was split between responsive operation and needing repeated taps to wake it.
P2
Product 2: Schlage Sense Pro
4.3
The disappearing touch panel looks advanced and keeps the exterior clean. Its minimal presentation can make operation less obvious to first-time users.
User access management
P1
Product 1: eufy Video Smart Lock S330
5.0
User management evidence was positive, especially around quickly adding additional users.
P2
Product 2: Schlage Sense Pro
5.0
Apple Home and Schlage controls make it easy to create temporary PINs, scheduled access, and digital keys. Reviewers especially valued flexible access for visitors and neighbors.
Value and Price
P1
Product 1: eufy Video Smart Lock S330
4.2
Most reviewers considered the price fair for the combined lock, camera, doorbell, fingerprint, and no-extra-fee package.
P2
Product 2: Schlage Sense Pro
2.4
At roughly $400, the lock is among the most expensive residential smart locks reviewed. Enthusiasts may accept the premium for design and UWB speed, but several reviewers considered the price difficult to justify.
Wi-Fi
P1
Product 1: eufy Video Smart Lock S330
5.0
Wi-Fi performance had limited but strong evidence, with one reviewer reporting no live-view latency.
P2
Product 2: Schlage Sense Pro
4.6
Built-in Wi-Fi provides direct remote connectivity and useful backup alongside Matter over Thread. Reviewers viewed this as an advantage over locks that require a separate hub for out-of-home control.
