Really, very honest for its price. Sturdy, for its size, quality construction, connected immediately with Samsung tablet, silent and good feel on the keys. The keys only have English letters (of course, you can write in Greek - I read such a question somewhere and laughed! A good hack is to write the Greek letters with a permanent marker if you can't find them). The mouse, also great, has 3 "response speed" settings, I needed to set it to the 3rd (the highest) for it to respond correctly, easy process, you will find it in the user and setup instructions. Silent and quite comfortable in hand. Both have on/off switches and the battery is not at risk.

3 stars since I can't give 2.5.
Well-designed and user-friendly
the keyboard is relatively fast, the mouse might as well be eaten by the cat. After waiting, it doesn't wake up and you have to turn it off and on from the button to bring it back to life.
The distance I use them is half a meter from the PC
