Cheap is not a problem.

Yesterday someone commented on the message and asked Xiao Bian. There is no recommendation for the mouse and keyboard set. For a long time, when Xiao Bian was in the push configuration, he simply gave the budget of the mouse and keyboard set, but he never mentioned exactly what kind of keyboard and mouse The suit is worth choosing, well, then push it today for reference.

001

The big return is more pleased

The largest number of carriage returns may be the right keypad, but what's the relationship? Believe that there are few people using the right keypad button? The hit return car is even more cost-effective when blind hitting, at least Xiaobian has always felt that the large return is very convenient.

002

The keycap should not be loose

The looseness of the keycap is caused by the dual function of the design and the use of materials. The keyboard is uncomfortable to use for a long time. The passage sense is also vague, and the percussion is very uncomfortable and the service life is not high. Keyboard, avoid it.

003

F key function or not?

Some keyboards, on the basis of the original F1 ~ F12 function keys, also added the second column of multimedia control functions, Xiao Bian feels like a tasteless to this design. Because during the operation, you also need to press the FN function key to trigger the corresponding multimedia function in the corresponding press F1 ~ F12 key, it is too much trouble, if you really want to provide convenience for the user, why not set up independent Multimedia shortcuts?

004

Battery 5 or 7?

Some mice use the 5th battery (AA), and the keyboard is mostly 7 (AAA), in fact, the essential difference is not great. However, Xiao Bian leans towards No. 7. First, it is convenient to change the unity. There is no need to buy two types of batteries for backup. The second is that the total weight of the No. 7 battery is lighter, especially when used in a mouse.

005

In addition, I do not know if you noticed that the general keyboard and mouse set in the keyboard is mostly 104/108 key, which is the design with the rightmost numeric keypad, Xiao Bian has been thinking, if it is a standard 87-key keyboard Just fine - the distance between the left and right hands is shorter, the operation is more convenient, and the little partner who plays the game must understand what I say. Of course, the wireless keyboard with a small keyboard is not without, but many are non-87 key design, the most significant feature is that the arrow keys move below the right shift, resulting in cramped operation, and particularly easy to misuse, Xiao Bian really do not like.

006

The other is that the basic functions of the mice in many sets of keyboard and mouse are simply too poor. There are no buttons for page turning (forward/backward) left and right. This operation is not very convenient. I hope the mouse can be a little bit more. Function is good.

Finally, Xiao Bian recommends three price points for everyone to choose.

50 yuan level

Fuller MK850 wireless mouse and keyboard set

007

Advantages: unique keycap design, comfortable feel

Inadequate: mouse button soft, need to get used to

Price: 59 yuan

100 yuan level

Logitech MK275 Wireless Optical Mouse Kit

008

Advantages: perfect function, special multimedia function keys

Inadequate: keyboard keystrokes are slightly shorter, hitting comfort generally

Price: 109 yuan

200 yuan level

Microsoft 900 Wireless Keyboard Kit

009

Advantages: Lightweight and percussive

Insufficient: The primary keypad, arrow keypad, and keypad keypad are compressed at intervals, making them easy to touch

Price: 179 yuan

In addition to these, of course, there are many key and mouse sets to choose from, if you have a good recommendation, comment area message! what? Is there any cheaper? This question is actually very easy to answer: There are a lot of 30 yuan more than a mouse and keyboard set, and it is wireless. However, Xiaobian really can't recommend it. He used to talk about feelings.
