The best way is to improve the control of the equipment to the control of the brand. If its equipment is not up to standard, how can it be a reliable brand?

1. Screening of elements for response selection
Safety>Quality>Function>Suitability>Appearance, never put the cart before the horse.
2. Don`t be greedy for petty gains.
The popular price is 2,000-4,000, and some online brands have 999 package installations that can be used, but the requirements do not need to be too high. Forget about the fingerprint lock that costs a few hundred yuan on a certain treasure. Let`s just use the original mechanical lock, which is safer.
3. Choose a brand
Don`t worry if you don`t know the quality of the brand. Let`s ask Du Niang for now. Small brands like to be produced together with big brands to set off their own popularity. Niu X brands are inevitable in the vague correspondence, and they will appear many times. Circle the brands that have been named many times or the brands that have been named very expensive.
4. After deciding on the brand, choose a classic model
Regardless of brands, big or small, as long as they have been engaged in lock making for more than 10 years, they will have classic models. This lock is definitely the most stable among these brands, and the series of products developed for this purpose can also be trusted.
5. Physical purchase and after-sales emphasis
There are many retail outlets across the country, so purchasing in physical stores is the safest option. Door locks are of a different kind, and after-sales service is extremely urgent. If you are not a well-known brand and have not yet implemented services, don`t ask for trouble. Don`t put too much faith in the lavish promises of platform merchants and your own luck. In the event of an emergency, no localized 24-hour door-to-door service is guaranteed.
6. Do not install it yourself
There is no need to do it yourself in order to save hundreds of dollars in installation fees, otherwise there will be quality problems later, and no brand will come to your door for free after-sales service. Moreover, the installation is not professional, and the hidden dangers are huge.
