I showed trust in the company. It was my mistake. Many times I type and it gets stuck. The screen doesn't display anything from what I write (so I don't have a direct image for mistakes or corrections or, in general, for the correct formatting of the text) and after a few seconds, all the words suddenly appear together. If you are someone who types fast (like me), then it is torture.
Furthermore, the distance that the manufacturer claims the wireless communication is guaranteed is simply not true. I brought the keyboard closer to the USB input where I have inserted the stick for the connection and still nothing. I brought it closer, and closer, I kept moving it. I almost brought it right above it and still the wireless communication is a torment.
My trust in this particular company has been greatly shaken.

I bought it 4 months ago and I have absolutely no problem. Since it belongs to my office, it is used daily and for long periods of time. The keys are of good quality, as well as the mouse. I have not encountered any connectivity issues or delays, no matter how long I leave them idle. Perhaps the only negative is that in reality, it is a lighter shade of gray than it appears in the packaging. In conclusion, for its price, it is a very good purchase.

I bought it about a month ago for around €25 and today I bought a Microsoft one for €40 to do my work. It required excessive pressure on the keys to write something, resulting in typing half the letters than what was pressed. It took twice as long to write a text. Noisy, cheap plastic and didn't fit well in half a meter. The mouse was the same, sometimes it worked and sometimes it didn't. I didn't want to spend more money and ended up buying 2 keyboards to do my work.

The keys are quite hard. It is not pleasant if you have to type for a long time. It would also help if it had backlight indicators.
However, it is an economical choice, so you don't have the highest demands.
The mouse is satisfactory.

First time writing a review for a keyboard. I'm writing the review as soon as I broke it. Both the keyboard and the mouse. It is the worst electrical device that has passed through my hands and the only one that pushed me to the limits of my patience. If there is even a piece of A4 paper between the "keyboard" and the wireless receiver, it doesn't work. If there is a mobile phone nearby, it doesn't work. For every 5% decrease in battery, you have to get within 10 centimeters of the receiver. I wanted a keyboard and got the bad disease. The computer tower was literally 20 centimeters away from the keyboard. Don't even think about it, unless you enjoy chemotherapy.

Stay away from this product.
The major disadvantage is that it does not have indicator lights to show if the CAPS LOCK, SCROLL, etc. are activated, so I bought the 'status tray' to have these indications.

It does not have LED for any function (Caps lock, Num lock, SCR lock), generally I can't say that I am disappointed since I knew what I bought, but I expected something more.. It does not have a good connection over 3 meters with the USB, resulting in it not working, the mouse has a very low DPI so it is purely for very simple use. I bought it for the Smart TV, I would not recommend it for PC for any reason.

Unfortunately, the keyboard needs to be 10 centimeters long and without any obstruction from the tower/usb in order to work properly. Otherwise, it either freezes or gets stuck on a command and repeats it indefinitely.

I have it for a year. The mouse scroll sticks incredibly when pressed from a certain point onwards, which almost renders it useless. The keyboard, although it has good build quality, did not help me type faster and obviously is not suitable for gaming at all. It also sticks from a certain point onwards, meaning that some of the keys I use a lot, such as the escape and spacebar, do not respond sometimes, which forces me to press them multiple times for them to work. I even changed the batteries, thinking that might be the issue, but it's still the same.

Guys, I have had this set for about a year. The keyboard didn't impress me, I expected it to be better, or rather it disappointed me because sometimes the keys don't respond as I would like and it's not convenient for fast typing. I noticed that I make a lot of mistakes.
As for the mouse....... it's the worst. The scroll stops responding after a while, but the worst of all is that it's not accurate. Meaning, if you try to move it along a line to the right without deviating from it, it will make other small movements and it's extremely annoying. I thought it had to do with its sensitivity, I tried it on different surfaces, downloaded drivers... nothing.
Stay away!!!!

In my case, I have even hit it forcefully against the wall and it didn't suffer any damage...
It's perfect for office use. Definitely not for gaming... The battery still hasn't run out after 6 months of use.

Very good, the only negative, as everyone says, is that it doesn't have LED indicators for caps lock, num lock, etc. and that the Mute and volume buttons are on fn+f4, fn+f5, etc. and not separate dedicated buttons. Other than that, it is quiet with a nice feel.. but it doesn't seem very sturdy.

The keyboard is for throwing away.
It freezes incredibly in games, even on the desktop.
The only good thing it has is that it doesn't make noise.
Very bad product....

Very nice set!
The keyboard is top-notch!!!
It is very quiet and has a very fast response to the keys.
The only downside is that it does not have an on/off and caps lock indicator.
The mouse is also excellent.
It has an on/off...
click/wheel and the size is just right.
For me, who types very fast, it is flawless.
For work, it is perfect and you can hardly hear it.
I wouldn't change it for anything.
While all the other Logitech products make a little more noise, this one is almost zero.
ATTENTION!!
This is only for work and especially for those who type fast.
For gaming, get another one, this one doesn't do it.
