Every time I see the keyboard is always unable to extricate themselves, the last time I used Sairui or Sairui 6G many years ago, in fact, left me with an impression is not good. The black shaft is very sticky, not like the feeling of the original shaft, and then manually replaced all the red shafts. As a result, the keyboard was overwhelmed and dropped. Lead to a circuit board keyboard. Throw it under the bed and never feel lucky.
This time I saw Aunt pushing the APEX M650, which was a bit turbulent. then. . . Buy buy buy!
The red axis bought this time, in fact, the duck 2018s that was used very early was the red axis, too light, the impression was not very good, but the time is older, already forgotten the feeling of the red axis. In addition to green or grey, recently used, the Vajradhara means that it is close to the level of graduation, and that the red axis is totally unaccommodating. Therefore, the evaluation of the red axis may appear to be very subjective. Please also understand.
The following into the open box
Keyboard box, everyone has a box out of the box, I will also bring a box of frontal photos. 
Various so-called technologies. 
The seal is complete and brand new. 
Open, very simple, no protection against shock foam. 
Take off the plastic skin, take out all the accessories (in fact, the plastic bag on the left side of the picture and the instructions below) actually did not pull the button device, it is too tricky. This is seriously inconsistent with common sense. 
The line is not nylon nor is it a key line separation. 
USB interface is not actually gold-plated. I can only say that the only thing on this line is the shielded magnetic ring. 
On the back, it was disappointing again that there weren’t many angles in the qualifying. 
Can not be separated from the key line to close-up 
The mats are well-received, with a total of four, two high and two bottoms, which directly avoid the possibility of a sudden collapse of the keyboard when used intensely. 
Height difference comes as a close-up. Because I'm used to the lower keyboard, I'm just throwing the high floor mat directly into the box. 
Using a floating design of the keycap, it is easier to get hygiene. 
After power on, random colors. 
Remove the keycap and reveal the real body. Red shaft, Sairui own goods, QS2 axis body, RGB lamp, unknown pressure, feel lighter than the original red (original red in impression) 
Spacebars, etc. use satellite axes. In fact, I still like the way to balance the bar. 
The side of the keyboard is very nice. I personally like this photo at this angle. 
The back of the last keycap. ABS double plastic material. When purchasing this keyboard, the PBT keycap was selected, but due to the general quality of the keycap, it was necessary to reconfigure a pair of keycaps to use it over time. 
It took a long time for the driver to drive. Can not open the official website, the old ENGINE 3 without this keyboard driver, completely unrecognized. So the driver part cannot be evaluated. Wait a few days to see if there is any domestic network disk.
Summarize briefly:
advantage:
RGB lighting effect is still good.
Sairui own axis can also feel. It looks slightly lighter than the original red.
In addition to the keycap, the keyboard itself works well.
Disadvantages:
The line is too out of grade, no key line separation, no nylon thread, no gold plated interface.
700 yuan actual feelings are not low prices.
The keycap feels too general and the workmanship is generally too.
The driver can't find it.
