If you want to buy a smart door lock with high performance-to-price ratio, you can’t just look at the price, and you can’t lock it with miscellaneous brands. It is important to sort out your own lock buying needs according to the structure of family members and choose a suitable smart door lock without pursuing more intelligent functions.

　　For example, if there are old people or children at home, we should try our best to avoid ordinary fingerprint password locks and choose smart door locks with 3D face recognition and finger vein recognition.

　　For another example, since there is already a security system at home, the cat’s eye of the smart door lock is of little use, so it is completely unnecessary to choose this kind of door lock.

　　High cost performance does not mean low price, which means that you can’t buy a good brand of smart door locks. Xiaomi is the representative of high cost performance and high quality.

　　Of course, in addition to Xiaomi, there are VOC, Yunmi, Good Wife and other 800-900 yuan, so you can buy a high-quality smart door lock.

　　For example, Xiaomi smart door lock E10, VOC smart door lock X6 and Yunmi smart door lock eLinK2C not only have high quality, but also their prices are not higher than those in 900 yuan.
