Complete product, well finished electronics but slightly brittle plastics. The instructions are minimal, very difficult to understand how it works when you know nothing in alarm. Once we have understood is actually simple to program. A more precise manual would not be a luxury. triggering the alarm (at least the phone call) during blackouts ... and not on the first programmed number ... not really understand. The siren emits red light every minute, not possible to disable. The built-in siren is very powerful, it is imperative a real mermaid. One can not apparently off.
