Access history is available in some setups (and was highlighted in early coverage), but in practice it can depend on the hub and platform, and not every controller app exposes detailed logs.
Event history is a consistent strength, with multiple reviewers highlighting detailed lock and camera logs that can identify who unlocked the door by fingerprint or code.
Reviews note no built-in alarm/siren, so there is no siren loudness benefit to rely on.
App support is inconsistent: some versions rely on a smart-home hub app rather than a dedicated Kwikset app, which can limit advanced controls like remote code creation on certain platforms.
The Eufy app is broadly praised for setup, live view, quick lock controls, access management, and clear event history, with few complaints beyond battery-related settings tradeoffs.
Auto-relock/auto-lock features are commonly praised for convenience and worked consistently in testing, but toggling settings may require opening the interior panel and using small switches.
Auto-lock is widely described as reliable and flexible, with adjustable timers and scheduling, though it is timer-based rather than true door-position sensing.
Wrong-try protection appears well implemented, letting owners lock out further attempts after repeated bad fingerprints or PIN entries.
The adjustable deadbolt and removable fit pieces help it adapt to common backset and bore variations on standard doors.
Powered by four AA batteries with low-battery warnings and external 9V jump terminals for emergencies; battery life reports vary (some cite roughly 5 to 6 months), and battery access can require partial disassembly.
Battery life is the biggest unresolved weakness: light use can be respectable, but several reviewers saw much shorter runtimes than the 8-12 month marketing claim once motion, video, and notifications were active.
Multiple reviews explicitly note there is no Bluetooth, so there is no phone-proximity unlock or key fob option.
Bluetooth helps with setup and is mentioned by some reviewers as an available unlock path, though Wi-Fi and fingerprint are the primary day-to-day methods.
The exterior build is described as sturdy and the mechanism proved reliable in use, but at least one reviewer reported sloppy bolt machining that made installation harder.
Build quality is generally rated highly, with reviewers calling the exterior solid, premium-looking, and well made for a lock-camera combo.
Reviewers generally liked the sharp 2K image, usable night vision, fast live view, and subscription-free local storage, but the camera side remains more compromised than a dedicated video doorbell because field of view, package visibility, and button discoverability can vary a lot by door layout.
Reviews note no full door-open/closed alerting, but some describe auto-lock behavior that only triggers when the door is closed and may beep when it is not fully shut.
Reviews indicate the E330 lacks true door-open and door-closed sensing, so auto-lock relies on timers instead of confirming the door position.
It fits standard deadbolt doors well, but compatibility gets worse with deep jambs, screen doors, unusual spacing, or layouts that block the camera's view.
If you are replacing another Kwikset deadbolt, the footprint and standard door prep can make swaps easier, with minimal changes to the door.
Some installations reuse the existing strike plate or fit the current bore cleanly, but others require minor modification or a new strike fit.
Z-Wave Plus versions cite over-the-air firmware update capability, but overall functionality remains intentionally minimalist and still depends on the hub ecosystem.
Fingerprint entry is one of the product's clearest wins, repeatedly described as fast, accurate, and the preferred way to unlock.
Lineup comparisons indicate the E330 does not offer the location-based auto features found on higher-tier Eufy models.
Obsidian stores up to 16 codes on the standalone model and up to 30 codes on connected versions, with 4 to 8 digits per code; code limits and scheduling features vary by model and ecosystem.
Guest access is flexible, with permanent, temporary, scheduled, and one-time code options that reviewers found genuinely useful.
Most smart features require a compatible Z-Wave hub; without it, Obsidian behaves like a standalone keypad deadbolt.
A hub is optional rather than required: the lock works on its own, while HomeBase 3 mainly adds AI features, storage flexibility, and ecosystem extras.
Many reviewers found setup straightforward with good hardware options, but others ran into alignment issues, confusing instructions, or a tricky handing/calibration step that required rework.
Installation is usually quick and straightforward for standard doors, often landing in the 10-20 minute range, though edge cases can require minor door work.
Obsidian is keywayless, so there is no physical key override if electronics fail; the emergency fallback is the external 9V jump terminals plus your PIN.
The hidden physical key and external USB-C emergency power option give the E330 credible backup access if the battery runs down.
The illuminated touchscreen keypad is central to the design and is generally responsive and easy to use, though a few reviewers note it can take multiple touches to wake.
The keypad works well and supports scramble PIN entry, but several reviewers note that the button area can be hard for visitors to find in the dark.
The physical key backup is useful, but the cylinder cannot be rekeyed, which several reviewers see as a practical downside.
Unlocking is generally quick once the keypad wakes, but some reviewers reported slower wake behavior and slightly slower operation in hot, sunny conditions.
Locking and unlocking are generally quick, especially by fingerprint, with several reviewers describing the response as near-instant or sub-second.
Motor noise is noticeable to some reviewers, who describe the mechanism as loud during operation.
Limited direct commentary suggests the motor is reasonably quick and quiet, but this is not as heavily discussed as fingerprint speed or battery drain.
Across reviews, the lock generally operated consistently without jamming, and the auto-relock feature performed reliably when enabled.
The lock mechanism itself is consistently dependable in reviews, with few complaints about failed locking or unlocking once properly installed and calibrated.
The lock provides audio/LED indicators (including low-battery alerts) and hub apps can show lock state, but native, lock-specific push notifications are limited and platform-dependent.
Notifications are a strong point, with repeated praise for fast alerts from motion events, doorbell presses, and lock actions.
Removing the keyway reduces exposure to key-based attacks, but otherwise Obsidian is a standard deadbolt without advanced intrusion sensing or active defense features.
Evidence is limited but positive, including BHMA-related claims and durability figures that suggest a sturdier-than-average smart lock build.
Keywayless entry reduces the risk of traditional picking and bump-key attacks; reviews do not provide an explicit drill-resistance rating.
When paired to a Z-Wave hub, reviewers were able to lock/unlock and check status remotely, but code management and other functions can be restricted by the chosen platform.
Remote locking, unlocking, live view, and answering the door from the app all work well and are central to the product's appeal.
SecureScreen (decoy/random digits) helps prevent fingerprint-based code guessing, and Z-Wave versions mention encryption; the keywayless design also removes common key-based attack vectors like bump keys.
Integration centers on Z-Wave hubs (such as SmartThings, Wink, and Control4) with Alexa/Google voice control typically routed through that hub; multiple reviews call out missing native HomeKit support.
Integration is good but not universal: Alexa and Google are commonly supported, HomeBase 3 adds more capability, and HomeKit support is notably absent.
The glossy, minimalist touch surface looks premium on modern doors but can smudge; SecureScreen and anti-fingerprint coatings help reduce obvious fingerprint trails.
The touch-sensitive keypad is responsive and modern, though nighttime discoverability is not as polished as on some dedicated doorbells.
You can add/remove PINs and use an optional master code, but advanced guest access controls (expiring or scheduled codes) are limited or unavailable on some models and hubs.
User management is robust, supporting admins, shared users, remote passcode assignment, and sizeable limits for codes and fingerprints.
Pricing is mid-to-premium for a touchscreen deadbolt; value is better if you already own a Z-Wave hub, but paying extra for a hub and living with limited code controls can reduce perceived value.
Value is mixed: the combined lock-camera-doorbell design and no-subscription local storage are appealing, but the price stings more when battery life or fit issues reduce the benefit.
Voice control generally works for locking and status checks through Alexa/Google when paired with a hub, but unlocking by voice is often restricted for security.
Voice control through Alexa or Google is commonly supported and useful for basic lock commands, though it is more of a convenience layer than a standout feature.
Support and warranty coverage look adequate rather than exceptional, with a one-year warranty mentioned and at least one battery-drain support interaction that did not fully solve the issue.
The black exterior can absorb heat in direct sun; at least one reviewer noted it can get hot to the touch and may slow slightly under high heat.
Weather resistance is generally viewed as solid for outdoor use, with repeated IP65 mentions and positive rain-use feedback, even if one comparison suggested a lower resistance tier than the S330.
There is no built-in Wi-Fi; remote access typically depends on Z-Wave plus a hub rather than direct Wi-Fi connectivity.
Wi-Fi performance is typically stable once connected, with fast remote access and alerts, but setup expects a 2.4 GHz network.
