The order came in excellent condition. I connected it within 10 seconds, there was no failure. In general, everything is fine as always! It's not the first time I ordered it. The only thing that can be added is that the store is very serious, responsible, conscientious and sociable. Many thanks to the seller for everything! Anyone who wants to buy a quality product is sure that he will buy from this seller. Buy here, or you will lose!

Дорогой Aliexpress! Я думаю, что не точные переводы описаний товаров тут созданы умышленно. Если продавец хотел, то сделал бы описание товара очень точным. Это очень не дружественно со стороны магазина поддерживать и поощрять не точные переводы чтобы вводить в небольшие заблуждения. В результате не точного описания мне пришлось купить не соответствующий и ненужный мне товар в этом магазине - сенсор двери, который не работает с WI-FI и требуется дополнительная дорогостоящая покупка управляющего блока. Это уже не первый раз когда заказывается не такой товар с неудовлетворительными для конкретных целей характеристиками. Теперь я буду всегда сообщать о плохом описании товара потому что это делает неприятности покупателям.
