Reasons to purchase

The idea of ​​having a fever on the red axis has been prepared for pitting for a long time (all are fake). Occasionally, I saw Weibo's new flagship of Zhuo Wei 2 and adopted a new shaft body that I have not seen before. Derived the current prism shaft body. At the same time, I also compared the optical axis of the domestic Shuangfeiyan and found that the principle of the difference, the prism axis using a complete transceiver device to trigger the key, the optical axis using the axis cut off the grating ray to trigger. Seemingly use Light, but the principle is different.

Prismatic axis is divided into two kinds of axis

Transparent shaft (red touch)

Orange shaft (kind of blue axis)

The final purchase occurred because of 3 points.

Shaft aspect

It was the CD502S with redness of 599, and the transparent shaft, that is, the red touch, before reading some knowledge about the prism axis, haha, at first I also thought that it was similar to the optical axis of the old factory Shuangfeiyan for some time ago. The grating cuts the beam to trigger it. After careful understanding, we found that the prism axis uses the reflection of light to trigger, an interesting setting.

The biggest difference is that the prism axis has two devices to send and receive, as shown in the picture (I got a screenshot in the video, more intuitive)

However, there are not many manufacturers using this axial solution in the market, but they are all very high-end, such as Zhuowei's flagship second generation, Ducky and other brands, and the positioning is still relatively high-end.

Keyboard appearance

Suspended design, positioning version for aluminum alloy, using a hand care design, hand care surface treatment process for the piano paint, the left hand part of the IF design award information, the right side of the red logo light (can also adjust the color) The surface is smooth. (I am white version)

The keycap is a set of ABS keycaps for the male model characters. It is very common, and it is also a spit slot. The price of 599 is still not used on this grade, but because of fan reaction, it has already begun to develop the fuel keycap. It is worth looking forward to.

Whether it is the application of paint or aluminum alloy, it can be seen from the factory and commercial materials.

Hand feeling

How does the prism shaft feel? Different, there is no excess metal plate in the axis, the direct axis is positioned under the axis seat and the wall of the upper cover, and the direct spring is used to construct the touch, but it is surprisingly easy to use and it can be used for a long time. It is still smooth and resilient.

And life expectancy has improved.

The feel is soft, and the pressure is biased toward the G red axis (Jadalong), but the rebound is very powerful, which is stronger than G.

Daejeon’s use of the satellite axis is a bit shaky, but it is not meat. It may also be to sacrifice the shaft to make a sacrifice. However, it can continue to improve.

to sum up

Highlights:

1. Prismatic shaft life is longer, personally look right, because the red axis uses the spring to directly build the feel, the spring is not bad basically no problem (I have 2 1992 rubbish cherry black shaft keyboard, the shaft body is finished, The spring is still very powerful.)

2. Noise is lower, popular point is faster.

3. The light guide, this is very cool, the shaft of the light is the use of internal light guide, do not astigmatism, take the heart of the design.

4. Development of pressure sensing, I developed the possibility of development of pressure sensing in the video of the Dutch team, because there is a transceiver device, not only can simply accept light, but also feel the strength of light, thus redefining the trigger of the key value. .

5.pcb waterproof coating, can have a certain waterproof capacity.

Disadvantages and shortcomings:

The keycap features are not obvious enough, and the material does not match the price.

Big keys are a bit shaky.

The practicality of hand rest is not strong.


In general, the price of 599, as an introduction, is worth a try. It is worth trying.
