I have had this set for a long time and I will evaluate each one separately.
1. The keyboard started to not work on a vertical line from the number 9 to the omega and below. I thought something might be stuck, so I opened it. After cleaning it, it started working again.
2. The mouse squeaks a lot but it is sturdy. The side buttons have opposite functions, meaning the back button goes forward and the forward button goes back. There is a mistake on the circuit board. The LEDs do not turn off, so they bother me at night while sleeping. It rarely freezes during sudden movements at maximum DPI.
3. The headphones simply work, they don't have any bass or quality. I generally don't use them, but sometimes they do the job during parties with my Guild.
4. The mousepad is good, nice with red seams.
Overall conclusion: I realized that sooner or later, every time I try to save money, something will not go well and I end up spending more. I ordered the ck104 and the motospeed v30 mouse. No, I don't spend money on famous brands, I like to support small companies that are trying. And I'm not a pro gamer either.
Conclusion: I do not recommend it, but it's okay for a start.

First, it should be noted that the details of the set are not orange as depicted here, but red. I emphasize this in case you want to match the color theme of your computer with the colors of the set.

1. Keyboard:
The quality of the keyboard is quite good. It includes multimedia keys on each side of the keyboard, as well as two lifting clips on the back. However, the characters displayed on the keys are not particularly bold, especially on the red keys, and gave me the impression that they would fade after extensive use. Nice typing feel and relatively quiet, with a small exception for the space key.

2. Mouse:
Nice feel on the clicks and relatively quiet. It also includes side buttons, which I assumed have a de facto go back and go forward function when navigating a webpage, but when I pressed them, nothing happened. It is possible that they require programming or some configuration, but the set does not include drivers (DVD, link to the company's website). They may have some different function that I did not have the chance to discover. The mouse also has interchangeable lighting that gives a nice touch to the set.

3. Mousepad:
Visually impressive mousepad with red details and a red stitch on its outline. Keep it away from sharp objects to avoid cutting any threads and damaging the stitch. The mouse does not "glide" on it, but overall it provides a much better feel than the bare desk surface. It does its job.

4. Headset:
The "gem" of the set. It requires careful handling because judging solely from its construction, it is made to break. When I connected it for the first time to test it while listening to a song, I noticed that the voices of the singers sounded distant and low, while the musical instruments sounded crystal clear. I also noticed the same issue while watching videos. Eventually, the problem was solved after some time when I pulled the plug slightly out of the green audio port. However, my troubles did not end there. After conducting some tests, I found out that the stereo was not working. Normally, two different audio channels should be heard, one from each speaker of the headset. In this case, the two audio channels were heard simultaneously from the right speaker. The problem was also confirmed by the technicians of the store, as I sent the set back to where it came from and now I am waiting for a replacement or compensation.

In general, it is difficult to say no to such a set, especially at this price. However, quantity overshadows quality. You must be prepared to accept the problems that will arise over time. But the worst is when the problems appear as soon as you open the package of the set. Be cautious and have taken the necessary measures to act promptly in case the set is defective.

EDIT: The set was replaced within two days. The new headset works properly and without any issues. The previous mouse was also defective, as it turned out, since the side buttons on the new mouse have the expected function (go back, go forward). It is worth noting that every time I have turned off my computer, the mouse lighting continues to work and I have to pull the cable.

UPDATE 12/01/2019: The 'D' key of the keyboard does not respond on the first attempt and sometimes requires extra pressure. I no longer use the mouse wheel because it usually doesn't respond, but the rare times it does, I get the opposite result (scrolling up becomes scrolling down for a very short time). The headphone cable remains tangled like the first day, and when I increase the volume, there is a brief decrease in sound before reaching the desired result. Overall, I didn't expect anything more from the set, and at the moment, I am looking for something better.

I was eagerly anticipating the set, especially for the keyboard and headphones. The keyboard exceeded my expectations, especially in terms of the key press feel and its appearance, as well as its numerous and convenient buttons. However, it is worth noting that the image advertising the product with orange keys does not match the reality, which is red keys on the keyboard. Ultimately, it is an excellent and exceptional keyboard. No one can deny that. However, the headphones were a complete disappointment, my friends.... Except for their positive elements, such as their appearance with the red cushions and their microphone, the sound is very low. Their maximum volume is equivalent to only 50% of the speakers on a desktop... As I mentioned before, it is disappointing. Finally, the mouse is excellent with an exceptional design and a satisfying click feel, as well as illumination. The mousepad is also very good because up close it is impressive with great material and a design better than what the advertising image shows, and it is a large size. Overall, it is a very good set, except for the headphones which really annoyed me, and I am seriously considering throwing them off my balcony. Let the game begin, brahs.
