Compare Desloc D110 Plus Smart Lock vs Aqara U50 Smart Lock

Built-in Wi-Fi was praised for direct connectivity and remote use, and one follow-up noted updates that improved Wi-Fi stability and power use.

Wi-Fi was a recurring limitation because the U50 lacks built-in Wi-Fi and needs a hub for remote access and fuller smart-home features.

Smart-home integration was the main limitation: Alexa and Google were supported, but reviewers missed HomeKit, Matter, IFTTT, or broader security-system support.

Smart-home support is a major selling point, with praise for HomeKey, HomeKit, Matter, Alexa, Google, and broad ecosystem flexibility, tempered by hub/Bluetooth tradeoffs.

Notifications were useful for awareness and security, but one reviewer wanted push notifications instead of emergency emails that went to spam.

Notifications were useful to reviewers for lock activity, people coming home, low battery, and related automation triggers.

The touch surface/keypad was praised as responsive, well lit, and visually integrated into the front panel.

Touch input is mostly good, especially swipe-to-lock, but reviewers noted that waking the panel before entry can be mildly confusing.

Voice control worked well in the reviews that tested it, especially with Alexa and Google Assistant.

Voice control had limited but positive outcome evidence, with a reviewer showing a voice-assisted unlock working after PIN confirmation.

The app was generally described as simple, easy, and user-friendly, with good access controls and setup flow.

The Aqara app is viewed as powerful, especially for automations, status checks, and advanced settings, with repeated praise for its breadth of options.

Reviewers consistently liked that no separate hub or gateway is required.

Hub feedback was mixed: some Apple Home users can avoid an Aqara hub, but several reviewers disliked needing one for full features, volume controls, or broader integrations.

Fingerprint access was one of the most praised areas, with many fast and accurate reports, though PCWorld found it hit-and-miss.

The missing fingerprint reader was the biggest tradeoff versus the U100; some reviewers missed it, while others accepted it as part of the lower price.

Door-sense was a clear weakness because reviewers noted there is no door sensor and the bolt can extend while the door is open.

Door-sense split reviewers: one was impressed by the built-in sensor, while another liked the idea but found it not reliable enough for exact door position.

Remote access was a major convenience, especially for managing the lock away from home or unlocking for guests.

Remote access was mixed: it gave peace of mind when working, but some reviewers disliked Bluetooth limitations or slower Home app control.

One reviewer cautioned that very thick doors may require modification even though standard doors worked well.

Door fit received positive but limited evidence: one reviewer said it worked in many doors and was not hard to install.

Keypad impressions were mixed: PCMag found it responsive and well-lit, PCWorld found it slow to wake, and another liked the soft glow.

The keypad earned strong marks for lighting, large numbers, easy code entry, and fast response, despite a few wake-up quirks.

Motor feel was mixed: one reviewer found it smooth and quiet, while another warned that over-tightening could make the bolt struggle.

The locking mechanism was praised in limited evidence for moving smoothly once installation was aligned correctly.

Auto-lock was praised for peace of mind and convenience, but multiple reviewers flagged limits around timing and open-door behavior.

Auto-lock is one of the U50's clearest strengths, with reviewers praising improved behavior, passage-style controls, and dependable nighttime locking.

Access logs were useful for seeing lock history, entry timing, and who entered.

The log feature earned praise because it lets reviewers see when people lock and unlock the door and helps track comings and goings.

The 90-day follow-up praised Desloc for frequent firmware updates and meaningful improvements.

Aqara's updated periodic passcode controls were praised as a meaningful improvement that brought the lock in line with other manufacturers.

One reviewer specifically reported no jamming during several days of testing.

Jam or abnormal-deadbolt feedback was positive in limited testing, with the lock alerting the reviewer when the door did not latch properly.

User access management was a strong point, with praise for simple schedules, temporary codes, and control over different users.

User management is useful for household and guest codes, though Apple Home controls were described as bare-bones compared with Aqara's app.

Speed was mostly positive for voice and remote response, though one reviewer found it fast but slower than pricier locks.

Unlocking was consistently described as quick, especially with HomeKey, keypad, and improved hub/Matter response paths.

Physical resistance evidence was moderate: reviewers cited BHMA certification and durability, but one emphasized it is the lowest acceptable commercial level.

Residential security was treated as adequate rather than premium, with one reviewer saying the lock was good enough for most homes.

Guest access was praised for one-pass, scheduled, IC-card, and Airbnb-style temporary access options.

Guest access is a major strength, with praise for multiple codes, temporary or periodic access, NFC access, and practical use for family, visitors, dog walkers, and Airbnb hosts.

Weather resistance was generally viewed positively, including rain/outdoor use, though one reviewer called the IP54 rating tame.

Weather resistance was viewed as sufficient for outdoor use, though one review noted the lower dust rating as a cost-cutting compromise.

Industrial design was praised as sleek, ergonomic, modern, and premium-looking rather than overly bulky.

Design opinions were mixed: reviewers liked the modern black look and sleek layout, but several called it bulky, plain, hard to read from a distance, or limited in color options.

Most reviewers described the lock as solid, sturdy, or durable for the price, while one found the construction quality questionable.

Build quality generally impressed reviewers through sturdy materials and solid feel, though one noted some cheaper-feeling plastic elements.

Installation was usually described as quick and simple, but one reviewer had jammed bolts and another noted a short cord and over-tightening sensitivity.

Installation and setup were consistently praised as easy, fast, and approachable, though there were isolated caveats about door fit and instructions.

Value was the broadest strength because most reviewers saw a lot of features for the price, although PCWorld rejected the value claim after testing.

Reviewers strongly agreed that the U50 is excellent value, repeatedly calling it affordable, a great deal, and one of the best budget HomeKey smart locks.

Backup mechanical keys were valued as a practical fallback, especially for power loss.

Physical key backup and rekeying were praised, especially the hidden keyhole and the convenience of matching existing keys.

Reliability was a strength across several reviews, with reports of perfect testing, stable 90-day use, and natural daily fit.

Reliability feedback was strong: the lock kept working without the hub, worked smoothly with Apple devices, and automatically locked as expected.

Battery impressions were good overall but not exceptional, ranging from solid and efficient to fine but not incredible.

Battery feedback was positive overall, with reviewers calling the life a thumbs up, appreciating ordinary AA batteries, and noting useful low-battery warnings.

Alarm and sound controls are useful and adjustable, but one reviewer found the default voice volume very loud and hub-dependent to change.

Failed-attempt lockout drew criticism from one reviewer because the settings and behavior were not clearly adjustable or explained.

Palm vein recognition was not included, and one reviewer missed that faster, convenient method from another lock.

The hidden keyhole cover was praised as an extra security measure against casual lock-picking visibility.

Security features such as anti-peeping and anti-hijacking were viewed as useful or reassuring, with PCMag also noting enhanced security options.

Bluetooth is a backup and low-power option, but reviewers consistently preferred Zigbee or hub-based connections for faster, steadier response.

Reviewers repeatedly liked the small on-lock display, describing it as helpful for setup, status, battery, alerts, and local control, though one saw it as basic rather than groundbreaking.

Warranty evidence was limited and negative: one reviewer warned that replacing the cylinder could leave the user on their own with warranty coverage.
