preface
In the past, the 4 major items that I had to travel on business were "hand key money", that is, ID cards, mobile phones, keys, wallets; Even if it is a temporary outing, you must also take the mobile phone wallet and key, but now it is good, mobile payment makes everyone no longer bring a wallet, many people go out is the mobile phone, the key; And the smart door lock launched in recent years has also solved the problem of no longer having to carry the key with you, although some people's homes have been replaced with smart door locks, but careful observation of most of the family has actually been using the original mechanical lock, the reason why most people have not changed the smart door lock, in fact, one of the main reasons is the price of smart door locks, other reasons are worried about the durability of the door locks, the convenience of use and the shape of the door locks, etc. And I also changed a fingerprint lock for a few hundred dollars in the home a year or two ago, at that time it was just a simple way to not want to bring the key, but one is old-fashioned, the second is that its structure is simple, can not be used on the Internet, and even the lock has no lock cylinder inside, so I am very worried about which day this lock is broken, is it necessary to smash the lock to open the door? After this toss of mine, I found that buying something still needs to be studied well, especially the cost performance of the product, the use of functions, etc., and this time I was particularly fortunate to get the Xiaomi smart door lock M20, I quickly replaced the new lock, today's article content is the use experience of this Xiaomi smart door lock M20 article.

A smart door lock in addition to its inner door lock and external door lock, the most important thing is the automatic lock body and lock cylinder, although I did not take the lock body apart to see, but from the lock body surface workmanship, details, to the lock body in the hand inside the heavy texture, can feel that the workmanship is quite solid, and this Millet smart door lock M20 with the lock cylinder is also a security level of C-level in-line mechanical lock cylinder, to ensure that you can also use the two emergency keys it is equipped with in extreme cases to open the door lock.
