Unfortunately, it has a major connection problem and disconnects almost immediately. Either the keyboard connects but not the mouse. As soon as I experienced this, I put it back in its box and on the shelf in the library. Unacceptable purchase!!!

For 20 euros, it is a very nice wireless silent set. I have tested it up to about 3.5 meters and it works. The mouse takes 2 AAA batteries and the keyboard takes another 2. The mouse has a switch on/off, but the keyboard does not. The mouse is quiet, but indeed small and its scroll wheel has a bit of resistance. I use it for simple tasks, so it doesn't bother me even though I have big hands. The keyboard is also quite quiet. I will update on battery life. Overall, I recommend it for anyone who wants simple use and doesn't have high demands.

value for money set. The keys have immediate response and the mouse as well. Both are silent. For the 23 euros I bought them, no matter how long they last in everyday office use, they will have paid off their money.

The keyboard delivers everything it promises. As for the mouse that comes with it, it is not good. It is too small to be comfortable for the hand, and its laser even picks up when it is in the air, which makes it annoying for movements that require lifting the mouse.

It is clearly a value for money product. It is not intended for hardcore gamers, nor is it suitable for heavy office use.
Its positives are that the keys are soft and silent, it has an on/off switch on both the keyboard and the mouse, it has multimedia keys (although not separate ones), and it has an LED indicator for caps lock.
As for the negatives, I would mention the build quality. Although it has holes for anti-spill and non-slip bases, the chassis is somewhat flexible when pressure is applied to the center.
I haven't had a chance to form an opinion on battery life (I've had them for 15 days). However, the automatic energy-saving power-off function works without the need to turn them off from the switch.

They are quite comfortable to use and both are quiet, neither the keyboard nor the mouse make much noise. They have a simple and functional design and I like that they have a decent weight that keeps them stable (they are not heavy, just not completely lightweight construction). The mouse has a good sensitivity. Especially for the price, they are value for money
