This keyboard turned out to be defective, not just once but twice! It had the same issue almost every time I opened it, with the keys in the entire row not working. These affected keys are shown in the photo and are the same on both keyboards. Luckily, I had Skroutz Plus, so they sent me a second one for free. However, from the second day onwards, it had the same problem as the first one. I called support and mentioned it to be covered. After that, I did a reset, but it seems like it needs another one. Another issue with this keyboard is that when I turn on my computer, it says "device malfunctioned" with an exclamation mark on Windows and requires spamming the keys for a few seconds (20) to turn on and work normally afterwards. I thought of not returning it since it works, but one day when my PC was in sleep mode, I tried to open it with the keyboard and it didn't respond even after many attempts. I simply clicked the mouse and it opened, but the keyboard remained unresponsive no matter how many buttons I pressed. Classic move, unplugged and plugged in the USB, and it worked, but it still has defects. After requesting a replacement, Skroutz arbitrarily decides to refund instead of replacing it. Anyway, if you get it and it works, even with the spamming to turn on, keep it, otherwise, get a refund because it's defective. As a keyboard, it's good when it works, but I had the misfortune of the 5 key getting stuck inside and making a spring sound many times. Lastly, the highlight is the wrist rest. It's soft with foam underneath and leather-like on top. I repeat, if it works, it's good, but are you willing to take that risk? (at least if you're not paying for shipping)

Positives:
- Greek company
- Immediate service from the company. I sent them an email with the problem I was facing and they solved it the same day.
- Smooth feeling on the keys and impeccable latency. At least for this price, I don't think I have any complaints.
- Wristrest. Very good in terms of ergonomics and stability, again for these prices. It also gives the feeling that it will withstand and not peel off in six months like some much more expensive ones.
- Swappable keys and sensors.
- It also came with a keycap puller.
- RGB

Negatives:
- Build quality. 100% plastic but I have no complaints. It may not look premium but it's good enough.
- The RGB could be a little better, maybe brighter.
- When I got it, the Alt and Windows keys were functioning backwards. As Zeroground pointed out to me, I did a reset on the keyboard by pressing the FN+ESC keys until the lighting started flashing, and then the keys worked correctly. Thank you Zeroground.

At the 40 euros I bought it for, I would buy it again without hesitation. I bought it for the PC I have at my country house, while at home I use the Razer Huntsman Tenkeyless. Just to understand that what I'm writing is based on experience with noteworthy keyboards at much higher budgets.

When I tried the keyboard, I realized after a few minutes that one key was not working. After coordinating with the store where I bought the keyboard, I sent it back and received a new one. The only problem I have with the new one is that it doesn't turn on when the computer starts. I tried a different port, but obviously, that wasn't the issue. I didn't change it because it didn't bother me too much since I discovered that if I turn off the system and completely power down the computer, pressing any key will turn it on normally at the next activation. In short, this particular model is quite defective. It's worth the money if you don't end up with a faulty one.

Update 2025

Another user reports exactly the same problem, and in more detail than I did. I have to say that after 3 years of use, I am relatively satisfied because I've gotten used to its flaws. If there weren't so many defects in these specific keyboards, it would be a clear 10/10. The actual rating, considering the defects it shows, is 4/10, as it's a hassle every time to do tricks to make the keyboard work.

I bought it for my son. I have a Corsair with brown Cherry switches. My experience with the Tornado is very good. The keys feel a bit tight, they don't have the "pop" of Cherry switches, like they have some damper. Maybe they will loosen up a bit over time? We'll see. The sound is satisfactory and not annoying at all (like the blue ones - but who consciously chooses blue switches?). The lighting is beautiful, not too intense.
The palm rest you just place wherever it suits you. It doesn't attach anywhere. And its height is excellent. No comparison to the useless plastic thing that Corsair has. Here it is truly useful and convenient.
For its price, it is very good.
Update: It lost a star (maybe even two now that I think about it) because, as mentioned, when I turn on the computer, only the IOKLM buttons light up, which, when pressed, produce random characters ASDFG and QWERTY. It can be fixed by disconnecting it from the computer. Unacceptable, regardless of the price.
Update 2: It has been replaced, and so far it has not shown the problem, so it regains its lost stars. Only time will tell

We have and we say. I received it on 8/10/21 and it has already caused me problems.
+ Very nice switches and stabilizers that don't make you feel like the plastic is rubbing against each other.
+ Decent program, nice effects, although it has its problems.
- Every time I press any button, it sounds like it's deaf inside. It sounds like I'm hitting a metal bottle. I tried putting something inside to make it quieter. The sound comes from the metal screwed onto the PCB. The rest of the keyboard is made of plastic.
- The keyboard almost never lights up with the computer, resulting in me spamming the spacebar hoping it wakes up.
- Due to the previous problem, sometimes after the keyboard wakes up, the keys "i, o, x, k, m," when pressed, also press the rest of the keys in the horizontal line. The only way I managed to fix this is by uninstalling the program from the computer.
- 4 minutes ago, before writing this review, the alt and windows keys had changed position on their own. I don't even know how I fixed it.
- I don't like the font used by zeroground.

I may have received a defective one, who knows. I haven't informed zeroground about it yet and I don't know if they will help me. I have bought other keyboards from zeroground like the satomi and didn't have such problems. However, in your position, I would be cautious.
