There are some things you need to consider while trying to buy the right mechanical keyboard.

Know the Common Terminologies

One of the critical aspects of buying a mechanical keyboard is getting used to the terms used by manufacturers. Here are some commonly used keyboard terminologies:

• Bump:

this is the substantive response received when you press a key. It lets you know your keypress is “registered” before getting to the bottom of the switch.

• X percent keyboards:

the percentage determines the size of a keyboard and its features. For instance,
— 75% means a layout that is miniature and has function keys.
— 65–70% means a “layout” that is miniature and has arrow keys making a total of 66 keys.
— 60% indicates a keyboard of 60 or 61 keys without function key row.
— Tenkey means a board of full size and has a number pad.
— Tenkeyless shows a board with a full size but doesn’t have a number pad.

• Click(y):

The noise a switch makes while you click on it.

• Feels:

A physical switch that a keyboard uses. It includes buckling spring and scissor switches.

• Travel distance:

The distance between a rest key and a pressed key.

– Decide the Major Use

Mechanical keyboards usually have switches according to your specific tasks. Some switches, for example, have short travel distance to enable you to click faster while others need full depress to actuate the key.

Gamers often go for the keyboards with full depression to avoid pressing the wrong buttons accidentally.

– Carefully Choose Switches

Switches are very crucial, as they play an essential role in your mechanical keyboard. You will need to know what you want in your mechanical keyboards such as the travel distance, the desired bump, and even the level of noise you can tolerate.

This factor will help you choose right. There are lots of switches available, but take a look at these common ones:

• Cherry MX blue:

This type of switch has short travel distance, which will help writers type faster and reduces finger fatigue. It actuates around the Midway and has a bump that lets you know you have registered a key.

• Cherry MX brown:

This switch also has short travel distance and actuates halfway, just like the blue. However, it is quieter, and that makes it an excellent option for the office.

Cherry MX black:

Gamers usually appreciate this switch type because it gives an audio and tactile response.

• Cherry MX red:

This switch also actuates Midway, but it does not have a bump. It gives a smooth feel and is easy to use.

Final Thoughts

Both K400 and K400 Plus mechanical keyboards have great features which make each of them unique, but K400 Plus seems to have an improved design and looks more aesthetic with longer battery life.

Notably, the K400 Plus is compatible with more operating systems aside from Windows. K400, which happens to be a great choice if you are using Windows OS, also seems to work well for some other operating systems, but it is not as versatile as its bigger counterpart.

While they share almost the same technical features, the absence of a USB range extender might be the deal-breaker for anybody looking to get the K400 Plus.
