Foreword
If you ask the ThinkPad's biggest feature, many people will answer the little red dot on the keyboard. I remember that my first laptop was the ThinkPad T61 (a decade has passed, and is still serving with her mother). None of the three companies that have worked in the past have been equipped with the ThinkPad T or X series. All along, I was very satisfied with the ThinkPad's keyboard, feel absolutely good on laptops and have a unique red dot. Although compared to those who use the little red dot more flexible than the mouse, the little red dot also added a lot of work efficiency to me when there is no mouse. First on the map for 10 years to serve the T61 to show feelings:
This time changing the computer keyboard is not a whim, it really can not stand the former - Logitech K400 Plus. Previously, in order to remotely manipulate the mouse, I bought this wireless keyboard with a touchpad. After buying it found two problems:
Touchpad speed is too slow. Already in Logitech tools, the speed of the touchpad is maximized, but you want to move the mouse from the lower left to the upper right of the screen. The fingers still need to be drawn three times on the touchpad.
The keyboard feel is not ideal. Originally replaced the previous mechanical keyboard is also considered at home typing is not much, and now the game is not too playable, feel almost tolerable. But the fact tells me that it is absolutely unbearable! I used Logitech's other membrane keyboards before, and I didn't feel that way. It's hard to get a fake keyboard.
The upcoming K400 Plus:
------------------------
Last week, I saw the protagonist who was out of the box in the “Good Things†worth buying. He suddenly felt that he was too late and chose the cheapest channel to start.

Well into the topic. The goods were sent from Beijing and it took three days. The following paper box is the one to get the hand, and the warranty is affixed to it:
The store also sent a computer Bluetooth adapter intimately:
Open the box to reveal the body:
The things in the box are clear, and come to Zhang Family (keyboard, Micro USB charging cable, and instructions):
Take out the keyboard, in addition to less the following touchpad, and the keyboard of the ThinkPad notebook is almost the same. The surface of the keyboard is frosted, and with that red, it's still pretty:
I couldn't help but press my hand and press it up. The feel is exactly the same as the keyboard of the ThinkPad notebook.
Behind the keyboard butt is the Micro USB charging interface, there is a switch on the side of the keyboard:
The keyboard is thin, but the texture is good and there is no feeling of floating:
There are two expandable feet at the bottom:
Try Ipad first. In just one second, the keyboard was seen on the search interface, and it was connected directly after clicking:
Try to hit a few words without feeling delayed:
Then even the Android phone is searched for the keyboard very soon. It only needs to use the keyboard to input the verification code when it is connected.
Similarly, typing does not feel delayed.
The last is of course the most important computer. My computer is a Windows 7 system, has already installed the bluetooth adapter, so opens the bluetooth tool directly to search for the new equipment, the procedure is similar to the Android system, needs to input the verification code. After connected, the computer will automatically download and install Lenovo's driver. After the completion, an icon will appear in the system tray. Click to set the sensitivity of the red dot.
After rebooting, after entering the Windows system, the keyboard is automatically connected after approximately 1-2 seconds. I tried typing first. Again, I didn't feel any delay. Then adjust the sensitivity of the next red dot, the distance to control the next mouse, no delay, speed is also my intention. As far as handling distances, I tried a distance of three meters, no problem.
to sum upadvantage:
Feel good
The red dot is very sensitive
Supports computers, IOS, Android phones and tablets
Can be used wirelessly to remotely control the computer
Disadvantages:
Can not use without entering the operating system, that is to say this guy can not let you enter the BIOS.
It takes a few seconds to disconnect and reconnect, and it occasionally becomes unstable (when writing this article, it encounters a repetitive input that appears to be plugging in and plugging in other USB devices).
After all, it's wireless, and the delay can't be said to be completely absent. Although I don't feel comfortable using it in general, in combination with the second point, I really need to use this keyboard to play competitive games.
Overall, I was quite satisfied with this keyboard, which satisfied the little demand of my opponent and the need for long-distance computer manipulation. I was full of feelings. If you like the ThinkPad's keyboard and red dot and want to check on a desktop or smart tablet or mobile phone, this keyboard is for you.
