A pretty good combo for the 45 euros I spent.
The keyboard looks the same as the ck 104.
In terms of RGB, as previous users have mentioned, it is not fully RGB. It has 7 colors that it cycles through. Personally, I think it's fine, I don't expect much more for this price. It has different modes that can be changed directly from the keyboard without using any software.
The keyboard I chose has Blue switches. As expected, these switches are noisy. For me, this is a positive because that's why I chose them. They have a slightly hard press and fast rebound. If you had a membrane keyboard before, it will take you 2-3 days to get used to it. (Friendly advice: if you don't want a noisy keyboard, stay away from Blue switches. I have read many negative reviews from people who didn't do proper market research and unfairly criticized these switches.)
I would have liked the cable to be a bit longer for more comfort, but for most people, it's fine.
In terms of construction, it's the best you can get for this price. After doing some research, I couldn't find any keyboard at this price that is as sturdy as this one.
Now, regarding the mouse, I don't have much to say.
It's a simple gaming mouse that looks similar to the motospeed v30, but internally they have nothing in common.
It has a button that adjusts the DPI and simultaneously changes colors. So, it's not practical to synchronize the mouse and keyboard to the same color.
In terms of comfort, I didn't notice any issues. It's quite smooth and doesn't give you the feeling that it sticks to the mousepad.
The side buttons are soft and easy to press.
Conclusion:
The keyboard undoubtedly has good quality and appearance.
The mouse is nothing extraordinary. It's just okay for getting your work done. Personally, in the future, I will replace it with a slightly better one that either has software or is more customizable in terms of its RGB.
For its price, the set is decent and there is nothing similar that strongly competes with it for under 50 euros.
