0. Preface
The first is to thank my grandmother for giving me this chance to participate in the test. After I tossed a lot of mechanical keyboards, I re-experienced the touch of a thin-film keyboard, and the Logitech K780 really did not fail to live up to my expectations. The specific experience will be detailed later.
Second, I personally have always had a good impression on the wireless keyboard. After all, they have passed the age of using computers to play games. They still like the neatness and simplicity of the desktop, and they don't like the feeling of tangled cables on the desktop. It's not that I haven't tried desktop organizers yet, but after a simple trial, it feels like it's normal, and the less the desktop or the line, the better.
Finally, I personally have a good opinion of Logitech's brand. However, it does not mean that I will only promote it like soft papers in assessment, and more as an independent user, a code farmer, to make a real evaluation of this product.
1. Brand
Logitech, the world's leading manufacturer of computer peripherals. With the development of ODMs and OEMs in the past, they gradually became bigger and bigger. At least half of the computer mice worldwide are called Logitech. And then also involved in a variety of hardware peripherals, such as gamepads, steering wheels, membrane keyboards, mechanical keyboards, a wide range of wireless keyboards, Bluetooth keyboards, computer cameras, etc., simply overbearing. (Part from Baidu Encyclopedia)
As one of the (I think) Peripherals, one of the Big Three of Peripherals, comparing the lamp factory's cool horse breathing lights, compared to the non-mainstream cool styles of the steel mills, only the obsessive quality and experience are enough. Excellent feel, precise positioning, durable and durable, a mouse can be used for a few years without any problem, except for the dirty point.
2. Appearance
2.1 Unpacking
My brother's friendship to help the top, gold glittering "to the value" seal is simply bright my eyes ... 
Tearing the package, faintly revealing a small side 
We peeled off the outer package, and the box of the blue-greenish-green color that was not clear enough was exposed. 
Compared with the box of the previous Gaussian GS87 keyboard, it is still a little bit smaller, but also a little bit thinner. 
But turn to the side to see. The seal has been broken and it is not known whether it is due to violent delivery. 
Open the box to reveal the whole picture (but the box opening is reversed, so the keyboard is reversed after opening. 
Unrequited me, re-jammed the box, carefully studied the details of the box packaging. For example, this shows that the keyboard supports linking multiple devices to facilitate switching between computers, tablets, and mobile phones. 
Side of the support for some of the operating system. 
Touted the key shape. (The drama is not as good as the actual experience. 
Again emphasize support for multiple operating systems. (Nothing else can be written yet? 
It is said that the battery life is invincible and it supports dual-link and Bluetooth. Very convenient. 
The process of taking out the keyboard was skipped, and a simple instruction for use was printed on the bottom of the keyboard box. 
The keyboard body still looks very textured. (Also feels, weighs 875g... 
On the simple back, only one battery compartment and one looked very comfortable. 
Open the battery compartment and show that you need 2 No. 7 batteries. The UNUP receiver is quietly placed inside. 
Give LOGO a close-up. 
2.2 Details
Let's take a look at the U.S. receiver. 
Exquisite LOGO. 
The most critical 123 switching keys for the keyboard. Supports simultaneous storage of 3 device connection information. 
As a composite function key supported by the dual system, the win key and the alt under the windows, and the opt and the spline under the macos, and the multi-system adaptation are very convenient. 
Round-up, nice-looking buttons, but it's not practical, it's easy to make mistakes (it may be a good thing to get used to it). At the top is the multimedia keypad. If you need to use the F key, you need to use the fn key in the lower left corner. Use the key combination. 
This has a power indicator, green. 
Below is the switch. 
Side, bracket. Very wide, suitable for most tablet devices. 
2.3 Comparison
Compared with the average 87 mechanical keyboard, the length is almost the same, there is not much difference. 
The width is wider than the mechanical keyboard. 
Thickness is an overwhelming mechanical keyboard, and my mother no longer has to worry about my tenosynovitis. 
The thickest stand is also shorter than the mechanical keyboard. 
At the same time, two devices (ipad mini + huawei mate7) are more than sufficient. 
The most surprising place, actually able to ask the support sp3! 
And the size of the location is very suitable, but also very solid, not at all unexpected, nor loose, perfect solution to the bed with sp3 when the keyboard is not good to make the embarrassment, simply greatly praise! 
Compare the thickness with the little things around. A certain star pen in the United States should be ignored. 
Speaking of thin, or sp3 keyboard to be thinner. 
3. Experience
3.1 Linking Devices
Have to say, K780 is done very well in the user experience, the link is very convenient, I use win10 link as an example.
Open win10's Bluetooth search, then long press the bluetooth button you want to help (123 white keys), and then jump out of the prompt to find the device after 2 seconds. 
Click on the paired device, then prompt the user to enter a few digits in the keyboard, then press the Enter key, the link is completed. 
The next time the user uses, directly press the white numeric keys to use the keyboard directly, which is very convenient, and the switching between multiple devices is also very smooth.
3.2 Typing input
The big round button is the key size of a full-size keyboard.
However, this is still the Tucao, because of the round button design, resulting in the gap between the button and the button is too large, but it leads to easy to touch. (Okay, please Tucao, I'm a remnant...
3.3 Traveling
This is a comparison of the 16L Arctic foxes used by girls and the men's thinkpads. 
When standing vertically, it looks as if everything is okay. 
But actually putting it in will take a long time, which will lead to deformation of the bag. The programmers still have a disadvantage in using this keyboard to move the office. 
Men's coders are pleased to see the black thinkpad, ibm smart earth, and other series of packaging it no pressure. (except a bit heavy) 
3.4 Desktop Organizer
(Although it is the most important event, I have used this as a title, but there is really nothing to say. A picture is worth a thousand words .)
Before... 
After... 
The next estimate is to match a more suitable wireless Bluetooth mouse...
4. Inadequacies
4.1. Multimedia keys are preferred. F-keys are required for fn key cooperation. The cart before the horse is upside down. First of all, I personally feel that multimedia keys are really convenient for most users, but after all, multimedia keys are not particularly commonly used keys, compared to most people still use this keyboard to access the windows system, the use of F zone The frequency should theoretically be higher. And the fn key is only on the left side, and there is no fn key on the right side, resulting in the use of F12 is bound to use both hands to use, especially inconvenient. (I am a low-end code farmer, occasionally involves the development of the previous stage, you need to press F12 key to open the debug mode)
4.2. The keys are loose, the longer the keys, the more obvious. Among them, the space bar is the most obvious, and the sound of pressing is very discordant. There is a slight rubbing noise, and the backspace button and the shift button are also obviously loose. The Enter button is slightly better and is more compact. Hope this is just an example of my keyboard.
4.3, lack of backlight. In contrast, even a sp3 keyboard can have a backlight effect, and it is difficult to imagine that such a keyboard actually has no backlight, which makes it difficult to use the keyboard in a low-light environment.
4.4. Heavier weight, not suitable for mobile use. Of course, this is also a problem with product positioning. There are relatively lighter and more portable versions available for purchase.
5. Purchase suggestion
The user community I made a simple division:
Users who need mobile office are not recommended , they are too heavy, and they lack portability, unlike other series.
Users who can use in a fixed location, in general , the experience is not so good, typing and gaming experience and the mechanical keyboard is still an essential gap.
Shape control users, recommended . It really looks good and doesn't need too much praise.
Users who need to support multiple devices at the same time and do not need to walk around are highly recommended .
In conclusion , the price/performance ratio is average, and it is only suitable for comparing specific user groups. It is not the best choice for general users.
6. Finally
Thank you for reading this review article. I am very sorry that you have tested relatively few keyboards due to more recent overtime work. If you have any questions after reading the article, please feel free to leave a comment below and I will reply you in time. If the problem is even unclear to me, I will use a few more days to review the information and reply. Thank you for your patience.
