Look down to see it | Why would I say 9.9 yuan mouse do not want to give me

In the 21st issue of the DIY old driver, Fengjin continued to talk to everyone about the last time. The last time we demolished the entry mouse for Logitech's m105, everyone saw the fireproof PCB board. Garbage mouse. In this issue, let's take a look at what a real junk mouse looks like. Why do I say that the 9.9 mouse mouse is not for me? The old driver drives the car everyday. This time we ride a small three-wheel ride. To sit firmly.

'PConline DIY old driver'The last time I opened the 29 Logitech m105, some netizens said in the following message that their 9.9 yuan mouse workmanship was the same as that of Logitech. Others said that this kind of mouse is e-waste. This time, Fengjin once again spent huge amounts of money to buy. Into a $ 9.9 mouse, Yes, we continue to take a look, Why do I say 9.9 mouse to me do not want.

The driving heart is really bloody. After all, 9.9 is enough for me to add a chicken leg. However, in order to talk to everyone about the low-end mouse, I have to get something to show you. Nothing is afraid of being an example. Hammer died.

A lot of low-cost mouse on the Internet, ah, even if I can search for only 5 dollars mouse, but after entering, will find the postage is more expensive than the mouse, forgetting to find a 9.9 mouse.

In fact, when looking for it, we can see that similar store evaluations are not high. Basically all three low stores (description/service/logistics are all green). Later, we reluctantly selected a store that is still decent, prompting us to pay an original price of 59 yuan. , Discount 49.1 yuan, amazing my boss.

But even if you choose a store that is still good at home, the bad review seems to be a bit more. But if I want to say that, buy such a mouse, but also want high quality is simply dreaming it. All this price, to pick up a bicycle ?

Soon after the mouse arrived, With the package also comes with a vouchers, praise back now 1 yuan, the boss is simply conscience, are so cheap but also return praise is also really nothing to say We have to calculate the cost of the boss. In general, courier companies charge the merchant's courier fee is definitely cheaper than we usually send courier, but also look at the price, but Generally speaking about 3-4 blocks. The box generally also a few cents, a mouse down only about 7.

However, after unpacking, I found that there wasn't a very pungent odor. I was surprised because I had previously bought a low-cost mouse. Even a mouse with more than ten pieces smells a pungent odor. This is due to the use of cheap, low-quality materials.

Ok, Whether it is the packaging or the mouse body, there is no manufacturer's logo, a typical three no product'Frame up, here is the focus of the exam ]The word "MADE IN CHINA" is only written at the bottom of the mouse, and there is no electronic product with a 3C, CE mark, but the mouse uses "FOR HOME OR OFFICE USE".

Since it is 9.9 yuan for three no products, its quality is surely so-so, don't think too much. At the seams, we can see stains and a lot of burrs.

Suddenly found that the mouse is actually a white mat, the general mouse pad is black, rarely seen white, so I would like to look closer and found that special mats and mouse bottom shell is one of the 'manual smile'. In other words, the mouse does not have a foot pad. The mouse directly designs the plastic pan at the foot pad part as a protruding part and acts as an 'integral foot pad'. This is a clever idea. This idea must be praised.

The next step is to remove the screws. After removing the screws on the back of the mouse, we can see the mouse body. The mouse can emit blue light. The two LED lights show blue light. To prevent the red light from the engine part, the manufacturers Intimate for the engine of the LED lamp beads battled a black sponge.

It can be seen that the accuracy of the upper and lower cover of the mold is really terrible, and there are various paint residues on the upper cover, and the stain is serious. The overall plastic part presents a kind of dark gray, and the typical plastic part made of recycled plastic is not known whether it is used or N-handed.

The wire is bare, loose and loose, and I am concerned about the possibility of being soldered off during use. The wheel does not have to be thought of. It is also black and grey. It is the first few rounds of recycling and there are still a lot of glitches. Not to mention what it feels like.

Now let's take a look at the core part. At first glance, The number of voids on the PCB is more than the number of soldered components , The reason why these mice can do such a low price, especially in the reduction of electronic components, as long as they can display a pointer, stability, accuracy?

The engine is a brand new version that I have not seen. In any case, I could not find a source for this engine. I asked the friends around me that I didn’t know anything about it. The micro-motion from Shenzhen was called “Shenzhen Chengdong Electronics Technology Co., Ltd.” I've been ignorant and have not heard of this manufacturer. However, my hand feels quite brittle. I don't know the lifespan geometry, and I haven't touched it before. The encoder is also no-nonsense.

It is this cheap pile of cheap plastic mouse that does not know where to produce components and parts, cut corners, and does not know how many times to recycle.

Then we look back at the Logitech m105 we've demolished last time, but it seems to be cheap, but the components used by the mouse are not parts that are produced by quality assurance manufacturers. Even the engine uses the original PAW. Series engine, micro-motion using a well-known Taiwanese manufacturers, Logitech is providing a three-year warranty.

PConline DIY old driver summary

Back to the title, why do I say that 9.9 mouse does not send me, such a mouse really is e-waste, second-hand or even N-hand plastic recycling parts, PCB board steal power, engine, micro-motion, encoders are all cheap products, Some even do not know the manufacturer.

According to the exchanges with relevant people in the industry, many mouse manufacturers can reduce the production cost of the cheapest mouse to as low as 6-7 pieces. The low-end industry is very confusing, and such a low cost naturally does not even think about how big it is. The guarantee. Take the engine, many no-name engine manufacturers have no technology to produce, buy 'foreign rubbish' after the dismantling package is also a common thing. Such components can have quality assurance?

And many of these '9.9-packed mouse's, according to my understanding of the source, there are so many, one of which is the foreign orders, the large quantities of millions of cheap mouses, and after tens of thousands of them were taken away, they disappeared. How to do the materials, can only be transferred to domestic sales after production, which is why many cheap mice are only marked with English characters.

In this way, there is no guarantee of quality. The mouse made from various foreign garbage components and N-recycled materials that do not yet know what kind of toxic substances are actually sent me do not want to.

The next time you want to know what you want to know, you can leave a message. Maybe the next time the old driver talks is what you want to know.
