BOTHSTAR Door Knobs YJ42 Editorial Review

### Editorial Review The Double Sided Keyless Door Knob Lock offers an innovative approach to home security, blending biometric technology with traditional access methods. Customers appreciate the added peace of mind this smart doorknob provides, particularly in households with children. The lock requires a key, code, or fingerprint for entry and exit, ensuring it remains secure at all times. With features like the ability to store 100 fingerprints and 50 codes, as well as a quick and efficient fingerprint reader, users generally find the doorknob to be user-friendly and convenient. Installation is straightforward, often completed within 15 minutes, thanks to clear instructions and voice-assisted programming. Many users have praised the versatility of the lock's settings, which allow for auto-locking, manual locking, and various unlocking scenarios tailored to different needs. The disguise code feature further enhances security by allowing users to enter their code within a random sequence of numbers, reducing the likelihood of unauthorized access. However, the product does face some critiques. Users have reported issues with the fingerprint scanner, particularly in rainy conditions, where it requires a dry surface to function correctly. Additionally, the synchronization feature between dual locks has been inConsistent, leading to extra programming steps for some. While the lock allows significant customization, other concerns arise from the manufacturer's support and quality control. Reports of early failure and poor customer service have led some to question the overall longevity of the product. Overall, while the Double Sided Keyless Door Knob Lock boasts remarkable features and functionality, potential buyers should be aware of possible drawbacks regarding weather resilience and customer support. ###
