Playing on the computer requires a good mouse! There are a lot of famous rats on the market. Originally, if you just picked one up, you would be able to use it without any scruples. But the annoying thing is that profiteers blind you and blind you with fakes. If you meet a Madaha customer and offer him some favors, he will be very grateful. Looking back, the rat will stay still even if it doesn't die.

Why don’t you ask the prawns around you for help? Ah, I am so thin. It doesn't matter, then just listen to me.

ZY 1-1999". The barcode of OK-052 is: 6924315300010. Fake products do not have barcodes.

The appearance of the genuine Shuangfeiyan mouse is very smooth, while the fake one is rough.

The fixing screw on the bottom of the genuine Shuangfeiyan mouse is not in the middle of the mouse, but slightly off. The fake ones are usually in the middle. And the screw holes at the bottom of the genuine product are small and deep, while the fake ones are thick and large.

At the door opening of the genuine Shuangfeiyan mouse ball, a pair of locks are clearly engraved on the left and right (one is open and the other is closed), while the fake ones do not have or are unclear.

Most of the integrated circuits on the fake circuit boards are HT6523, while the genuine ones are EMC84502 or TP8452.

The genuine product scrolls very quickly, while the fake product has a height difference of nearly 1 mm between the brackets on both sides of the horizontal transmission shaft. When pushing the mouse, it is very slow and the rolling ball often stops moving.

Logitech Mouse

The genuine product’s packaging box is beautifully printed and colorful. The box is stamped with "Swiss Brand, Swiss Technology". The white label at the bottom of the box of a high-end Logitech mouse has the product name, factory address and phone number in Chinese. The words "ISO 9001 Quality Assured Firm" are printed on the top of the box. The fake mouse doesn't have that logo. The outer shell manufacturing process of the real Logitech mouse is divided into two types: matte and full-gloss. Currently, most of them use matte outer shells, which are characterized by being shiny but not dazzling, and have a pearlescent feel. Most counterfeit Logitech mice have poor mold quality and poor manufacturing technology, so the mouse shell looks dull and has burrs at the seams.

Listen to the sounds made by mouse buttons. Real Logitech mouse buttons have a crisp sound and a flexible feel. The buttons of the fake mouse sound muffled and feel sticky. This is mainly due to the difference in the micro switches used by the two. The microswitch life of a real Logitech mouse reaches 5,000,000 times and can be used with confidence for 3 years.

Counterfeit mice generally don't last even a month.

Pay attention to the serial number (S/N number) on the label at the bottom of the mouse. Each Logitech mouse has a unique ID number, and the S/N number of each mouse is different. Counterfeit mice generally do not have S/N numbers or the S/N numbers of all products are exactly the same.

The details inside the mouse are different. We can turn the mouse over and unscrew the small round cover at the bottom of the mouse. For a real Logitech mouse, there should be a row of protruding numbers on the inside of the round cover. This is because Logitech has adopted advanced and complete material management for a long time. System, all product components have unique part numbers. And those factories that make fake mice are just small-scale manual workshops, and they don't take this into consideration at all. Therefore, by observing the small round cover, if there is no series of numbers on it, we can determine that it is fake.

Secondly, look at the fastening screws at the bottom of the mouse. The screws on real Logitech mice are specially treated and emit blue light. The screws used in the counterfeit mice are made of ordinary white iron. Identification is easier if you have access to the mouse. The circuit boards used in Logitech mice are generally multi-layer boards, produced using a fully automatic wave soldering surface mount process, and the main chip used is produced by Motorola. The counterfeit mouse uses a single-layer circuit board, which is welded by hand, and some of the components used are removed from the circuit boards of waste electrical appliances. There is a world of difference in the level of craftsmanship between the two, and they are easy to distinguish with the naked eye.
