Preface

I still remember when I was young, computers were not popular. At that time, I had the opportunity to touch the typewriter and press the key with 26 English letters quickly. It was crisp and full of science and technology. Later, every time I saw a typewriter lens in a movie, I became more and more fond of it. Later, with the popularity of computers, work and entertainment life can not be separated from the keyboard, but there is less wonderful sound of the past click click. In recent years, the emergence of mechanical keyboards has satisfied my little extravagant hope for mechanical feeling.

The overall line of the keys is bright, with narrow border design and clear edges and corners. The popular naked shaft design is adopted, and the keyboard steel plate is integrated with the upper cover, which can clearly and completely see the working mode of the mechanical shaft. The key cap is made of ABS material by two-color injection molding process, which is solid, wear-resistant and has good light transmittance.

The triangular solid status light in the upper right corner is designed with high recognition.

The yellow border on the side of the keyboard and the surrounding sports car design are really rare among many keyboards.

The heat sink on both sides of the keyboard accelerates the heat dissipation of the keyboard.

After simple disassembly, the internal workmanship is very neat.

4、 Experience evaluation

（1） Installation

The USB interface end has no obvious positive and negative marks, but has anti insertion and anti guide slots. At the same time, there is a reinforcement design, so even pulling the wire is not easy to fall off after it is plugged in. As we all know, the data line interface of electronic equipment often falls off, ages, wears, etc. during long-term use. The guide slot reinforcement design extends the service life of the keyboard. After connecting to the computer, you can use it without installing driver software.

（2） Light effect mode

It adopts the consistent yellow LED backlight with rich backlight control systems. After starting up, the keyboard light is first the snake and then all lights up.

2. Center diffusion and ripple mode FN+HOME

3. Left and right wave mode FN+Pageup

4. Breathing and lighting mode FN+Del

5. Custom mode FN+End

6. Normally on, backlight off mode FN+Pagedown

（3） Cloud driven

Unlike other mechanical keyboards, Jian Lv is also equipped with a cloud drive. To configure the 619 keyboard, you need to download and install firmware on the official website. After registration and login, you can see all the products owned by Jian Lv. Click the 619 keyboard to enter the detailed setting interface.

In the cloud drive, you can adjust the light effect in the 619 keyboard settings, including light mode, game backlight, light effect speed, and brightness level. The light mode enriches the backlight effect of the keyboard, making the light more cool. Moreover, the keyboard has a light memory function, so you don't have to worry about losing settings even if you accidentally plug or unplug the data cable.

Individual keys can also be set. The cloud drive settings of Jian Lv 619 are very interesting and need to be studied slowly.

（4） Practical experience

The keyboard integrates common shortcut keys and is printed with corresponding function icons, which can be used directly.

Ergonomically curved keyboard, smooth lines, scientific debugging. The actual experience of its typing feeling is that the keyboard is high, and the wrist is uncomfortable when typing for a long time. The sound of keys is weaker than that of game level mechanical keyboards, which means you can feel the snap of keys without disturbing people around you.

619 adopts full key collision free technology, so that pressing all keys at once will not cause key collision. In the e-sports that test accuracy and speed, no matter how fast the game operation is, it will not find the phenomenon of stuck failure. When playing games, the keyboard feels smooth and comfortable!

Finally, let's talk about the keyboard lighting. There are four levels of brightness. The lowest level is enough in the dark state. The effect of the brightest level is not very obvious in the daytime. However, taking some still life photos with it as the background still has a sense of mechanical technology.
