After many years as a Logitech user, both for the keyboard and the mouse, I have now switched to Microsoft. As Logitech has become a disappointment, mainly due to poor design and very few options if you want flat keys and Greek language support.
I didn't bother with the mouse at all, I threw it away immediately. It's a joke, but it's unthinkable to have a mouse without forward-back buttons nowadays.
Coming from the Logitech K360 with flat keys, which had a better layout with larger spaces that greatly helped with blind typing. In this one, the keys are slightly larger and lower, without spaces between the groups of keys, which makes it difficult, for example, to press 0 instead of the right arrow.
There is no ON/OFF switch, which is very useful if you want to clean the keyboard.
The receiver initially gave me trouble when connected through the screen on the back, and the keyboard didn't respond. Finally, I moved it to another position on the side and it works 90% okay.
However, it often disconnects and reconnects on its own for no reason.
The CAPS LOCK and NUM LOCK indicators appear in the bottom right corner only if you install the Microsoft software, and they are very small compared to the large central ones I had on the Logitech.
In short, a simple, beautiful flat keyboard without too many extras, with a useless mouse. It would be good to have an option without the mouse.
The keyboard layout is quite cramped, making blind typing difficult. It's been two months and I still make mistakes. This, along with the disconnects, has tired me out, and I simply hope that another better keyboard from a different brand will come out.
