Very good in feel, nice lighting not excessive, convenient USB port at the back...

Why 2 stars? Because during a period when I was away for an extended time from home and the keyboard was unused, it gradually started to malfunction, with double presses or specific keys not registering (e.g., the 7 on the numpad, the back arrow, etc.). As time goes by, I think more keys are losing their responsiveness. For the price and for its supposed build quality, unacceptable.

In 2 years it went off. 4-5 keys broke and cannot be replaced, as the 'teeth' broke and remained inside. The use I made was very mild and did not include gaming, continuous key pressing, etc

After a year of use:
It has the most pleasant keys of all the keyboards I have tried.
It's amazing for typing, but it's also annoying that it registers double presses.
In gaming use, it's super and I've never noticed a double press.
Since I type quite a bit and quickly, and the double presses annoy me, I only use it for gaming.
Overall, it's decent but requires very frequent cleaning.

It has the classic problem where the keys double press or don't work, other than that it's fine.

Very nice feel. The reason I gave 3 stars is due to the fact that the caps break easily over time from the switches and the only solution is either for them to pop off on their own or to glue them as a last resort.

It's a shame because it was a nice keyboard, I really liked the feel of the click... And after 3 years, it started doing what other users say, some keys double press and some don't press at all. For example, the left arrow key doesn't work, which had no use at all.

Chattering (double tapping or no response at all) on 3 buttons after a short gaming usage and not on the buttons that were chattering. The measurement was done with specialized software. Purchased on 24/9/2021.

After four years, the keyboard started to double click on the ctrl and space keys (as seen in my text). Of course, this is after daily, long hours of work, school, and gaming, which makes it susceptible to damage. However, there was no issue with buttons coming off or flying away, etc.
Pleasant for gaming, typing, high profile, the addition of a USB on the back of the keyboard is quite good and useful, good responsiveness. It is audible at night, but not clicky. The lighting is very good, discreet, and does not have RGB. Cleaning is not the easiest.
For the €80 I bought it for in 2020, it was a decent construction. If I manage to solve the double click issue, I will update.
Update 25/1/2024: The double click also affects other buttons, e.g., the numpad, which does not receive daily heavy use. It has nothing to do with the main buttons that are used.

After almost 4 years of use, I can say that I am quite satisfied (it was purchased for about €75) and I consider it worth the money. Except for the relatively difficult cleaning, it seemed very convenient to me. However, recently 1-2 buttons started to come off, so it's time to replace it

I'm not saying it's a good keyboard, it has a nice feel and sound, but it started having some issues even with light use. After a certain point, even though it was cleaned frequently, some keys started double-tapping on their own and getting stuck. It's unacceptable, unfortunately one of the keys completely stopped working to the point where I had to open it up and fix it myself. It's unacceptable for the price

double click / click not registering on 50% of the keys after 1 year of use. Personally, I find it unacceptable for such products to be in the hands of consumers. Poor quality..

As long as it works, it has good feel and response. As long as it works. I have bought two, in the first one some keys stopped working, within warranty, and there was an immediate replacement. In the second one, suddenly some keys stopped working again but it is now out of warranty. It is not worth its money, unfortunately, even though I am a fan of Logitech, this keyboard failed.

After a year and a half, it started doing what other users say. Some buttons were not working, like when you're in a fight and you want to press shift to run and it doesn't respond. And not only shift, but other buttons too. I would press codes that you can't see what you're typing and they would enter incorrectly, but not just once, but twice or three times. Overall, it has keyboard issues. Luckily, I was still under warranty, Logitech gives a two-year warranty, so I took it to the store where I bought it and they gave me store credit equal to the amount I purchased it for, so I could get another one. In the end, it's a pretty good gaming keyboard. Overall, avoid it.

I have it for almost 2 years... the buttons are pressed 2-3 times... the ctrl key doesn't even work sometimes...

In less than 1 year of use, the p and t keys write 2 letters with a single press. It also occasionally gets stuck and feels like a key is being held down.

Perhaps the worst keyboard you can get for the money. Extremely poor switches that easily break, this keyboard should cost at most 30-40 euros, not 70-80 euros. It has the worst switches compared to all keyboards in its price range. You'd be better off buying the motospeed ck108 for 50 euros a thousand times than this thing they called a "budget keyboard."

Unfortunately, as mentioned by others after three years of mild use, it started acting crazy, meaning either it doesn't respond to what you type or it enters it twice or three times. I wouldn't recommend it!!!

After 2 years, several key caps had broken "legs" that attach, some keys would type twice and some never at all... disappointment, sometimes it took me 1 minute to write ONE word!

For those whose stem is broken inside, take a thin needle, burn the tip and when it ignites, stick the needle into the broken stem, not all the way in, until it bites, leave it for a few seconds to cool with the needle stuck in, then pull and the needle will come out with the remaining piece inside... if it fails, repeat the process.

P.S: Never again Romer G Omrron..!

Stay away from this Keyboard.
It looks good, however, within a week (without any mistreatment) the 2 controls broke and they don't work anymore.
You can find MUCH better keyboards even for less money. Stay away.

Black carpet. The keys that I use a lot have started to come off and their plastic parts are breaking, and some others don't work at all. It barely lasted for about 6 months.

Do you remember the old Microsoft keyboards?
Once, I hit it so hard out of frustration that I thought nothing would be left. However, it managed to survive for many more years.
Fast forward many years later... I clean the devil with isopropyl alcohol and a toothbrush. I turn it upside down to let any debris fall, but instead, 5-6 keys fall, broken!!!!

Guys, the buttons after 1 year of use are pressed twice. Anything worse is not worth it compared to the motorcycles that are dogs!

I have it with a g305 Bluetooth. It is amazing and the construction is perfect. I thought about it a lot for no reason, I was thinking about Razer but in the end Logitech is just perfect! Don't think about it anymore, just get it.

Purchased in late October 2021. With moderate use by a child, some buttons started sticking (starting with the shift and space buttons). Taking off the keys to see what's happening, I noticed that the plastic caps on the underside attach to the button with very thin protrusions that easily break off and stay on the button.

Some of the protrusions fall inside the button, causing it to stick. Once the broken cap is removed, it obviously cannot be reattached.

Three months later, I have 2 broken caps and 3 more that stick, and I dare not lift them because I know the result.

There are no replacements available on the market. Not even in a cheap keyboard series...

Nice, but in the 3 months the first key broke... a key that is not used and constantly (of windows). It goes for repair and we'll see..

Update:
Finally, I got my money back... and I got the mx keys from logitech... The best decision I have made in choosing a keyboard

It has been over a year since I bought it. The "r" key started double typing, the left shift doesn't always work.
Unacceptable keyboard.
