In the process of home improvement, buying home appliances is like exploring unknown attractions, full of expectations.
When we give up buying a certain electrical appliance, there is always a trace of regret left in our hearts; And once you make a purchase decision, you often fall into regret. 
Many netizens have shared their experiences, mentioning four home appliances, which they will regret if they are installed, and regret if they are not installed. Have you ever been in such a situation? 
Before considering buying a smart toilet, people are often attracted by its high-end appearance, sense of technology and diverse functions, but after actual use, we have to face some problems that are difficult to ignore.
First of all, the headache is the discomfort of the spray pressure. The unexpected water pressure problem caused inconvenience in use, and a separate booster pump had to be installed to solve the problem. The overall structure of smart toilets and the scarcity of accessories make maintenance costs high, and every repair is distressing. This constant accumulation of expenses seems impossible to get rid of. 
Secondly, many people face the poor self-cleaning effect of smart toilets. Although it flushes automatically, many people overlook its self-cleaning function. The cleaning of the spout is handled manually, and over time, dirt accumulates more and more, which can be a major problem. 
In addition, the feeling of insufficient water flow and the problem of not rinsing cleanly are also disturbing. Frequent rinsing operations and a feeling of helplessness when unable to use make the whole experience extremely awkward. For some smart toilets, there is not even a manual flushing function, which adds to the dissatisfaction of users. 
When studying the choice of range hood, side-suction range hoods are gradually attracting people's attention. Compared with the traditional top-suction range hood, the biggest advantage of the side-suction range hood is that the oil smoke does not rush directly to the face. However, when we installed the side range hood, we regretted it, not because the side range hood itself is not good, but because we compared it with other types of range hoods in multiple scenarios and found that it was not so good. 
First of all, we want to talk about the most basic function of the range hood, which is to collect oil smoke. Compared with the top range hood, it must be admitted that the effect of the side range hood is slightly inferior. Although it is positioned low enough to absorb the smoke generated during stir-frying, the dispersed fumes are not ideal when cooking at high temperatures. 
Secondly, there is a noise problem with the side range hood. It's quite loud, with a lack of suction in low gears and very noisy in high gears. If the range hood is close to the bedroom, and there are elderly people or children at home, you need to think carefully. 
In addition, you will find that some of the more effective side hoods come with a baffle. This also raises some problems, especially the baffle that can block the view, unlike the top suction range hood, the side suction range hood cannot be completely hidden, and the appearance is not very ideal.
Of course, there are some ultra-thin side hoods on the market, but they may produce a dead spot of dust and oil, which is relatively troublesome to clean.
Before we want to buy a zero-cold water heater, we have to take into account the change of seasons.
Especially in winter, people are eager to enjoy comfortable hot water right away. Compared with traditional gas water heaters, zero-cold water gas water heaters have an additional water return device, through which the cold water in the pipes can be recollected and heated, realizing the desire to produce hot water instantly.
However, it is worth noting that in order to achieve the effect of instant hot water, zero-cold gas water heaters need to be constantly circulated, which virtually increases energy consumption, and the electricity cost is more than 60% higher than that of traditional gas water heaters, accompanied by louder noise. Therefore, it is not practical to simply consider saving on water bills lost in the early stage. If you don't use the zero cold water feature, how is it different from a traditional gas water heater? Moreover, if there is no large circulation, it will take a while for the small circulation to produce hot water, especially when the water outlet point is very close to the water heater, and it makes no difference whether a zero cold water heater is installed.
In addition, installing a zero-chill water heater requires the addition of return pipes, which are often pre-buried, which can be quite costly.
In addition, due to the short service life of zero cold water heaters, many brands of products are not mature and may have water leaks, which need to be repaired constantly. Therefore, when choosing a brand, be sure to do your research in advance to avoid unnecessary trouble. Of course, when you are waiting for water in the bath, you will feel that it is not as convenient as zero cold water, and the happiness of hot water in seconds is not a little bit.
When it comes to stir-fry machines, we have to think about the expectation that cooking will save time and effort. In the beginning, I had very high expectations for the stir-fry machine, and I often had all kinds of anticipation for it online. I purchased one last year, thinking that for a lazy person like me who is afraid of trouble, it should be an artifact-like existence. But as it turned out, it wasn't easy. Now. It has been forgotten in the corner by me.
For people who don't know how to cook at all, a stir-fry machine might help, but if you want to save time, I advise you to forget it. It's expensive, and you need to prepare the food yourself. Think about the time spent on cooking and basically spending time on preparing dishes, and you are already busy for an hour, leaving less than 5 minutes of stir-fry time? And the heat can't be adjusted according to the cuisine, so why bother! Those who have experienced it know that the food stir-fried by the automatic stir-fry machine tastes okay, but the appearance is really not ideal.
To put it bluntly, it has high requirements for the dish, and it works by making the dish by high temperature and constant stir-frying. Fragile dishes such as tofu are not suitable, and for some dishes with higher firmness, such as pork ribs, it is easy to scratch the coating in the pan.
In addition, mechanical stir-frying is not only noisy, but also very difficult to clean after stir-frying. After stir-frying, you will find that there are oil stains or vegetable leaves all around, which is very annoying. Although some stir-fry machines can be cleaned automatically, the lid is still greasy and needs to be cleaned twice.
Conclusion
When it comes to renovation, the choice is not absolute. The designs and products mentioned above have their advantages, but after weighing the actual situation, you can accept the problems they may have, so as to determine whether it is suitable for you.
