1. Mosquito-repellent incense

Although some designs are obviously unreasonable, they are spread from one person to another, and an anti-human design is promoted into an "industry standard". Mosquito-repellent incense is like this. It seems that unless the two pieces are entangled together, it would be embarrassing to say that it is mosquito-repellent incense. Even Ouchi masters in martial arts movies have to break it off.

This is the pain that many people have experienced. A good mosquito-repellent incense must use the entire resource space rationally and bundle them together. It is a smart design that ends up hurting all users.

2. Strong hooks

This kind of hook is not very sticky and will fall off over time, and it will leave prints on the wall that are difficult to remove. It is indeed a strong hook. Even if the hook is broken and broken, the adhesive surface attached to the wall will still stand.

However, strong hooks are still very active in the market, which is also due to its low price and affordable price.

3. Tableware labels

I believe many people have had this trouble. There are labels on the back of newly purchased tableware. If you peel off the layer of glue under the labels, it will not come off. It sticks to it and can't be washed off, making it look dirty. Especially for spoons, the contact surface is only that big and the labels are all over it. If you don't clean it, you won't be able to put it in your mouth without worry.

4. Trademarks on the collars of clothes

Many people feel uncomfortable with the labels on the back of their necks when they wear them after buying clothes, and have to use scissors to carefully remove them themselves. The logo design on the clothes is in a prickly position on the back of the neck, which many people cannot understand.

Many people complain that this design is anti-human - but from the perspective of the clothing industry, the back collar is almost the only optional position.

5. Spatial distribution of switches

In some places with small space, there are only one switch or two switches, so that there will be no mistakes in switching lights. But in a larger space, there will be many lights, and there will be more switches.

In daily life, we often see switches placed together. When it is necessary to turn off a designated row of lights, the wrong switch will always be turned off because of the switches arranged together. Moreover, lighting is generally required in a relatively dark environment. When the lights are turned on and off, the surrounding environment will become bright and dark, which will make people's eyes feel uncomfortable and cause eye pain.
