Today we will describe and fully analyze one of the most budgetary wired mice of our time. It's called Defender Optimum MB-160, made naturally in China... and its price is less than 1 thousand tenge. However, she is quite capable.

 

 

Although this mouse is still in production today, this copy is from 2018, so the packaging from it has not been preserved.

 

Outwardly inspect

 

This is a standard universal plastic mouse for both left-handed and right-handed people. Dimensions: 110 mm by 60 and 37 mm and the weight is clearly less than 100 grams.

 

There is nothing interesting or original in it - a standard body, left and right mouse buttons, a plastic scroll wheel, also with a button ...

 

A thin, medium-sized cable with a length of just over a meter with a USB connector ...

 

On the back side, the manufacturer's logo is true ... what manufacturer is it? This is so - a trademark! And who is the real manufacturer, we probably will not know at all.

 

We turn the mouse over and here again is a dull budget picture: four simple gliders (mouse legs), an oval cutout for a touch sensor. Paper label and on it: Defender logo, product model name Optimum MB-160. Article: 52160 Specification: Black, 3 buttons, 1000dpi. Power supply 5 volts less than 100 mA... Made in China. Serial number (for warranty card). There is also a manufacturer's sticker and according to it - the date of manufacture is September 2018 ...

 

Disassembly of the Defender Optimum MB-160 mouse It is under this sticker that one screw sits, which connects both halves of the case. We twist it. We remove the top cover - there is nothing interesting in it ... But we note that plastic is generally not bad used ... Well, this is all the rest of the content of the mouse ... familiar and banal ... electronics board with all the elements, a scroll wheel ... at the bottom there is a refractive plexiglass prism ...

 

We extract everything into the light of day ... Yes, everything is very primitive and not done very well. For example, the scroll is completely plastic. And the right mouse button is already buggy ...

 

MX8732 sensor It is on this chip that this mouse is based - MX8732 and this is USB / PS2 Single Chip Optical Mouse Sensor manufactured by LIZE Electronic. The board has the following markings: DOK-M203 and MX/FH8732 VCR 04 2017-03-18... In addition to the mentioned sensor chip (marked on it: N1704DD YS8105B), three BOMJS 0.05A 30V DC microbuttons and a BOJS 11 encoder... There is another resistor and two electrolytic capacitors. And also one crookedly soldered LED ...

 

The reverse side of the board is nothing interesting... the wires of the cable are soldered directly to the tracks of the board... V - red, G - white, D - green, C - black. conclusions

 

So, the optical USB mouse Defender Optimum MB-160 is completely disassembled and sent to the trash can (repairing one buggy button is not practical). What can we sum up from all the work done above? The simplest: this is a cheap and stripped-down mouse, from the category of the cheapest (but any amount can be in the price tags - according to the greed of the seller). Appointment corresponding - offices and other state institutions. The shape of the mouse is standard, which means it is quite comfortable for the hand. But the plastic scroll wheel no longer gives a feeling of comfort, although it's all a matter of habit. I also didn’t like the clicks of LMB and RMB - there is no smoothness and softness in them ... However, here my impressions do not have much value - after all, my mouse has already worked pretty well, and even partially broken ... and what it was like in new condition? I don't know that... that's why we finish the article as usual: I described what happened. I hope this information is useful to someone.

 

Of course, who is the real manufacturer of this mouse is unknown... Defender is just a trade mark that does not develop or produce anything by itself.
