## Before you buy

- The listing identifies the product as a C33 smart lock with a handle and calls it a deadbolt, while its A+ text calls it a Smart Lever Lock C33. The precise lock form is therefore inconsistent. Confirm the door hardware type and fit before buying. Apple HomeKit, IFTTT, and Matter are stated as unsupported at present. Customer reports of battery life and reliability vary, so plan for battery replacement and consider the reported connectivity and durability concerns.

## A good fit for

- Households wanting fingerprint and passcode entry options with app access and built-in Wi-Fi.
- Buyers whose doors match the listed bore, backset, and thickness dimensions.

## Customer feedback

Customer feedback praises the lock's appearance and features, especially keyless entry and app control, but reports substantial battery use and concerns about durability and connection loss. Fingerprint recognition, reliability, and ease of use draw mixed experiences. These reports matter for a Wi-Fi lock intended for everyday entry, and the stated eight-AA power supply makes battery upkeep a practical consideration. The overall rating distribution leans positive, but includes a meaningful share of low ratings and does not identify why individual customers rated it as they did.
- Positive themes: Customers praise the appearance, features, keyless entry options, and app control.
- Negative themes: Feedback reports high battery consumption, including reports that eight AA batteries last two to three months.
- Negative themes: Customers report some units breaking internally and Wi-Fi connectivity problems.
- Mixed feedback: Fingerprint recognition feedback is mixed, with reports of both successful use at different angles and unreliable performance.
- Mixed feedback: Customers differ on reliability and ease of use.
