The connectivity is very good on Windows. However, the mouse is of poor quality. Mine loses some clicks after 6 months of use. I would not buy it again.

After two weeks of use, the impressions are mixed.

The positives:
- Good Bluetooth connection without interruptions.
- Silent keyboard with a decent key travel that makes typing comfortable.
- Plenty of buttons that directly control various commands or applications in Windows (with a big BUT that I will analyze below).

The neutral points:
- Build quality. A typical plastic keyboard.
- Lack of keyboard tilt adjustment. For me personally, it's not an issue, but some may consider it a problem.

The negatives:
- Noisy mouse to the point of being frustrating.
- Lack of caps lock indicator. You have to test to see if you are typing in lowercase or uppercase.
- Lack of a print screen button. Yes, there is now the Win+W shortcut for screen capture, but in some cases, the print screen key can be faster.
- Something that might concern gamers is that the third row of keys is not positioned as usual. In most keyboards, the letter W is positioned 3/4 above the S and 1/4 above the A. Not here! It is right in the middle. For someone who plays 3D games or uses 3D design software that requires WASD navigation, this is an ergonomic flaw, as the hand struggles to adjust to the key layout.
- The worst of all has to do with the use of the buttons that directly control various commands. Most of them correspond to the function keys F1-F12, which have a dual function with the use of the Fn key, as in most laptops. However, here the default setting is the pre-configuration of different functions, and you have to use the Fn key for them to work as F1-F12. For many, this is not a big problem. For someone like me, who uses software with F1-F12 shortcuts, this is a nightmare, as I will either have to use an extra key each time or change the software settings. The problem could be solved with a simple mode selection option through the mouse & keyboard center, but no matter how much I searched, I didn't see this possibility.

In summary, 3 stars for all the ergonomic flaws I discovered.
