Currently, I am writing from this keyboard in order for you to understand the problem with the double clicks. The problem EXISTS. I bought the first keyboard in 2021, but it was replaced with a similar one within the warranty period (after convincing them that there is indeed a problem). And now, the second one, after a year and a half of use, shows exactly the same issue. Just don't buy it, not only will you waste your money, but you will also vent your frustration on those around you until the new RAZER arrives.

After about 2 years, I also started experiencing double-clicking issues. It's a shame because I really like its layout, the extra macro keys, multimedia functions, wrist rest, and the fact that it's wireless. But unfortunately, its build quality is simply poor for its price. It's entirely made of plastic, has no backlighting, and the Logitech switches are just of low quality. Mechanical keys are supposed to last forever, but here I am, after just 2 years, searching for a new keyboard again.

After about 6 months, the keys started sticking. What I mean is that a letter is pressed twice with one keystroke. If a keyboard that costs 130 euros has such issues, I don't think it's worth it.

On the positive side, the power management is good as I haven't had to change the batteries yet after using it almost daily for 7 months.

Update: I sent the keyboard back as defective and the response was that there is no problem and they will return it to me. So if you encounter this issue, it's your problem and you have to live with it. Do not buy - stay away.

The keyboard is very good!!! Stable and heavy. The quality of Logitech products is well-known. The software is average but known because I also have a mouse from the same company. The palm rest doesn't always help but it's good. Especially for a keyboard that costs 125 euros, I believe it wouldn't be difficult to make it removable. Overall, I am satisfied as a first experience with a mechanical keyboard. I got it for gaming and typing and it does its job well.

Quite a good keyboard. A huge upgrade for me. I had a Microsoft keyboard for 17 euros and I switched to a keyboard for 117 euros. Solid and heavy. The quality of Logitech products is well-known. The software is average, but I'm familiar with it because I also have a mouse from the same company.
I didn't like that when I press the keys, there is a metallic sound (like when two metals hit each other), not particularly loud but maybe annoying for me since it can be heard almost with every key press.
The palm rest doesn't always help and I would really like it to be removable. Especially for a keyboard that costs 117 euros, I believe it wouldn't be difficult for them to make it removable.

Update: After a year of daily use, the stickers indicating the letters have started to fade...

Why create such a revolutionary product, with multiple functions, macros, and a numpad (which many people inexplicably remove completely from their keyboards as if they're not needed, even though they are one of the most useful features), and then go and remove the lighting? Unacceptable, especially considering that the keys are stickered and wear out. Unacceptable for its price, and even if I were to put the keys aside, the lighting, come on guys. It doesn't have to be RGB, just have a simple lighting with 4 colors. It's a shame, I hope they release the same product without removing the macros and numpad, and simply have lighting. And the battery issue doesn't exist because the lighting can be turned off whenever someone wants to save battery, just like Corsair did with the Dark Core.

Very good, I have it for gaming, the only thing I would like for the money I gave is for the keys to be illuminated!
