Is the lock body of the anti theft door lock easy to break?

As long as it is a regular manufacturer's anti-theft door lock, the lock body is not easy to break, unless it has been opened violently, it will cause damage.

Security door: metal structure weldment.

Whether the quality is good or not depends mainly on whether the workers who make it are attentive or not.

The price of the brand door is high, the inspection process is more, and the quality problem: there are, but relatively few (probability), and the after-sales service is more complete.

Miscellaneous brands and even small workshops are processed locally privately, the price is low, and there may even be just a few people, almost no inspection process, apprentices get started, and the quality is ...... for themselves

Personal experience, figure profits, sold 6 miscellaneous D-level doors, four have problems, the manufacturer's attitude is bad, and there is no guarantee for after-sales.

Connoisseurs look at things, as for ordinary consumers, you just spend more money to buy brands, and you can't fix it if it's broken.
