In recent years, domestic peripheral manufacturers have sprung up. However, there are not many good and bad impressions. The number of people who can impress people is not much. Basically, they rely on non-mainstream appearances and various kinds of wonderful light pollution and low prices to attract customers.
Probably because of the price shocks of domestic peripheral brands, international peripheral brand names are now more and more indecisive.
For example, the famous lamp factory Python, the new version is launched one after another, but basically it is mostly worse.
The famous cherry also sells branded goods in China.
Even the famous American conscience, Logitech. . . Wait, Logitech does not seem to be the United States
Well, even the famous Gree congratulates Logitech. . . The Swiss conscience, Logitech, was so bewildered that it had betrayed the revolution.
In spring, I wrote an original
It was mentioned that I had a wireless mouse with a small size, which was extremely costly. She was very distressed and I recommended her Logitech M185, which is cheap and power saving.
As a result, she was ugly and there was no reason for this.
Until some time ago, she spent 10 years in the Microsoft wireless keyboard finally broke, and she finally decided to replace the wireless mouse and keyboard together.
So I recommended her Logitech MK270 wireless mouse and keyboard set, K270 keyboard + M185 mouse, very power.
Yes, you read it right. The mouse in the kit is still M185. It is so capricious.
Now it's about Logitech shrinking:Logitech MK270 looks like it is not young, has always been a good reputation for a very energy-saving wireless mouse and keyboard combination.
In the first half of the year, Aunt Zhang used the new Logitech MK275 measurement project. At the time, I thought it was an upgraded version of M270. I applied for one, but did not apply.
However, I soon discovered that things were wrong. The price of MK270 on Jingdong was as follows:
The price of MK275 is this:
Under normal circumstances, the upgrade version should be more expensive than the old version, and the new product will generally appear on the market price is high, why the MK275 come out on the cheaper than the MK270 20 dollars? There must be something tricky here.
Sure enough, there were several well-written reports in the public test report, such as the following.
The answer is that the MK270 and MK275 are both M185 mouse and K270 keyboards, but MK270 supports Logitech Unifying Technology, while MK275 does not support ULink, which is a shrinking version and therefore cheaper.
This is a sign of excellence. It can connect up to six devices to one receiver, which can save USB ports.
All Logitech peripherals that support superior technology have this conspicuous mark.
It is now an open box:I opened JD.com's website. Just as Logitech MK 270 had a discounted price, I finally paid 99 yuan, which was cheaper than usual MK275. I felt that I had made a lot of money, so I quickly placed an order.
Jingdong is very fast and it was delivered on the same day.
Then after half a month, during the eleventh period I went to play at Xiaoyi’s house and found a long Jingdong bag.
I was surprised: "You are very fashionable now, Xiao Yan. You will be shopping with Jingdong."
Xiao Xiao replied: "It was the last mouse and keyboard. I was afraid I wouldn't open it without using it."
I am very curious: "Your original keyboard is broken. What computer do you use for two weeks?"
Xiao Xiao replied: "The computer is also broken, waiting for you to redo the system."
So, I got an opportunity to unwind the Logitech MK270. 
Jingdong bag thrown, this is the front of the box.
The parameters on the back of the box.
Open the lid and there are 3 things in total.
Keyboard, mouse, nano receiver.
Remove the protective bag.
There are several holes on the back of the K270 keyboard. It is used to drain water. This keyboard does not mention waterproof performance, but in view of this, it should be waterproof. The upper left is the battery compartment.
Here are a few more close-ups:
Multimedia keypad. My favorite is the function that opens the calculator with one click.
Keypad and power switch area. This is actually very power-saving. It does not need to be switched on and off frequently. If you do not act for a long time, you will go to sleep and wake up automatically when you touch it.
The battery compartment requires 2 AAA batteries and the battery life is nominally 2 years. 
Positive M185 mouse.
M185 mouse underside. The above is the battery compartment, the battery life is nominal for 1 year.
Nano receiver, this mouse and keyboard set supports Logitech superior technology. . .
Wait, it doesn't seem right.
The MK270 suit should look like this:
Each of the above should have the icon of the Union.
And now it is like this, there is no trace of excellent union.
Now it’s time to expose the truth:My first reaction was: Didn't Logitech mean to give even a little orange pigment for the logo?
Obviously this is not the case, and the fact that it is simpler and more cruel has already emerged: The new version of the MK270 no longer supports superior technology.
I reopened the purchase page of Jingdong's MK270, and saw the following dialogue in the bottom of the purchase consultation:
Jingdong customer service has clearly answered that the MK270 now sold no longer supports Unitech.
In fact, the MK270 has become an ordinary plug-and-play wireless mouse and keyboard set.
In other words, there is no difference between the current MK270 and the MK275 in hardware and software. The only difference is the color:
The decorative color of MK270 is gray.
The decorative color of MK275 is blue-green.
Speaking, I think the color of MK275 looks better, but it is also cheaper for 20 dollars.
Fortunately fortunately, I didn't understand this, nor did I read Aunt Zhang. She didn't know that I was wasting her 20 bucks and buying a more ugly color.
It is now the last link:Logitech MK270 is dead, there is something burning paper. . . No, it is a direct purchase of the cheaper MK275.
Maybe there are valuable friends to ask, Logitech MK270/275 series so pit, there is necessary to buy it?
The answer is, yes, this mouse and keyboard set, especially the keyboard, has the following advantages:
1, full keyboard.
2, there are multimedia keys.
3, a good feel in the wireless keyboard.
4, light weight, keyboard 480 grams, 95 grams of mouse.
5, super battery life, keyboard for 2 years, mouse for 1 year.
6, the most critical is the cheap, often can achieve the following hundred yuan special price.
