Because the work needs a codeword, a good keyboard can be said to be a necessity. At the recommendation of the valued friends at the station, we started with several mechanical keyboards, such as the IKBC Poker 2 , the Xiaomi Yuemi keyboard and the Flico family. The red, green and tea axes all have experience, but for me For beginners, the pleasure of using keyboards with different axes gives me a very short time. After a long time, they feel almost the same.
Recently, my heart was getting longer. I was slightly annoyed by the USB HUB , keyboard, and HDD cables on the desktop. I also used the Magic Mouse that had been used for a while and I was thinking of a cheap and easy-to-use key. Rats, after some sort of selection, finally determined the target as an upgrade MK540 of Logitech Keyboard and Mouse Kit MK520.
I bought it at Jingdong, and the delivery speed is very fast. I received it the next morning after the order was placed. On the outside, the front is the rendering of the product. If there is a white style, it would be even cooler.
The back of the package is about some of the features of the product introduced, the system, the above is written to support Windows and Chrome , measured, Mac platform use without any problems.
In addition to the keyboard and mouse, there is a simple user manual for the package. Download the driver and turn on the bluetooth switch on the keyboard and mouse.
Since the keyboard and mouse are packaged together, they share a Bluetooth adapter, but they also found a small problem. There is no special storage hole on the keyboard and mouse. If you do not use it normally, you must pay attention to the Bluetooth adapter.
Both the keyboard and the mouse are powered by the No. 5 battery. The machine is also pre-installed. The official data shows that the keyboard can be used for 36 months. The mouse can be used for 18 months. It has a good battery life. Of course, the specific time varies from person to person.

The 
Compared to the previous mouse, silicone handles and pads were updated.

use The 
Because the original intention of buying this mouse and keyboard set is the code word, using Bluetooth connection, there are certain wireless interference factors, but I am the notebook HDMI connection to the big screen, so the Bluetooth receiver and the mouse and keyboard are very close, did not encounter any break The situation of the chain.
However, if you play the game, you will obviously feel the lack of frames, there is a certain delay; the keyboard experience is still good, hit the feel good, mute, and also support a certain amount of splashing.
Simply talk about its advantages and disadvantages.
