Товар вообще не получил. Продавец не отвечает. Вернули только половину и то алиэкспрес. Продавец полное дерьмо. Выводы за Вами. I did not receive the goods at all. Salesman does not answer. They returned only half and then aliexpress. The seller is full of shit. The conclusions are yours.
delay time isn't accurate, often even doesn't turn off at all. model pir-8 works much better.
