Получил 2 звонка и 1 кнопку, проверил, всё работает, прием отличный, пробивает металлический штакетник без проблем, батарейка была в комплекте (я просил продавца в заказе). Доставляли сдеком, приехал самым первым из всех заказов от 11.11, примерно за неделю. Отличный внешний вид. Быстрая установка. Мелодий много. Единственные 2 небольших недостатка: 1) шатается в розетке, слишком тонкое пластмассовое основание у вилки. 2) нет кнопки выключения звонка, нужно вынимать из розетки (например, на ночь).
