The electric kettle at home has been in use for nearly 15 years and still hasn't broken down. Due to various reasons, there are still three or four kettles at home that haven't been used yet. The service life of electrical products still needs to be designed; otherwise, even new ones won't be usable. What should I do if I need to replace this fingerprint lock with another one? Do I have to replace the door as well? If you buy a Samsung one and use it for ten years, this kind of fingerprint lock won't work. It's still the old-fashioned mechanical lock that's safe. It's best to install two layers of doors. It's either that kind of lock where the whole family can't escape in case of fire or an electronic lock. I didn't dare to change it until it was scrapped. I bought one that cost over a thousand and it was very durable. PDD, it's my fingerprint lock.
Good health for children + patient guidance = good grades. What do you think? There are too many factors contributing to poor academic performance, including family ties and the influence of the school environment. The most significant impact is still the parents' words and deeds. For instance, in many families, you watch your phone while your child is doing homework and even claim to supervise their studies. Can this really help them do well? In a community, there is a girl whose parents are divorced. Her mother doesn't work and is always busy dating. She often stays out all night during her primary school years. Now the girl is in a foreign language high school and has excellent grades. Reading still requires some talent, and not being able to read doesn't mean one can't make money. Everyone has different educational methods. Oh oh, is it useful to say those useless things? Don't hit the child. Mind your own business.
I have never bought anything on Pinduoduo. The price is there. There are design flaws. If cheap materials were used, it would be a ghost if the cheap goods bought online didn't break. I would never buy this kind of door lock in my life. I would rather trust machinery. I bought four fingerprint locks in 2019. Two of them broke in the same month this year. I tested them with a multimeter and found that the circuit boards were all broken by the same line. I guess the manufacturers have already designed the service life of this electronic component, haven't they? Isn't the traditional mechanical lock reliable? What brand is it? Please expose it to avoid falling into the trap of planned scrapping? Xixi Goods? Small workshops in electronics factories lack quality control. Brands are relatively better. I originally wanted to install a fingerprint and password lock, but later I saw in the news that many fingerprint and password locks failed the quality inspection. We didn't know which one was good. Well, in the end, I chose a mechanical lock…
