New Smart Invisible Door Lock, Hidden Lock Without Lock Hole Design, Invisible Remote Control Lock with 5 Remote Controllers

With extended use, the lock proves reliable — some buyers have had it installed for years without issues. However, the mechanism is partially plastic, requiring care during handling. Some users replaced the original screws with higher-quality ones to improve mounting stability. Synchronization with Tuya or SmartLife apps can be complicated, and instructions are only in English. Batteries are not included.

The main concern is mounting strength — thin screws anchoring the plate to the door and small screws connecting the plate to the lock are weak points. The lock functions as an additional barrier rather than a primary security solution. The proportion of negative ratings is low (3.3 %), but most reviews were written without installation or testing the product.
