The first impression is relatively good. The complete installation remains to be done. I will come back with further updates after I see its full functionality.

I had an old GSM alarm with RF traps and an external wireless siren for over 10 years, and I replaced the old panel with the PG-107, which has Wi-Fi, is smart (via the App), and can be controlled through Google Assistant. Of course, everything worked except for the old siren. All the magnetic traps and the infrared ones, along with the new ones, worked. The old siren functioned, but it had different commands, resulting in arming the new alarm but giving a disarm or SOS command to the siren. I had to order a new one from an international website that collaborated with the PG-107 (+20€).
Excellent solution and user-friendly, especially with the RFID tags. It is a good solution in combination with cameras and at the same time economical.
As for the drawbacks, I will mention the non-removable battery of the panel, which means that at some point, it will need to be opened to be replaced
