Goods quality-Sonoff produce good product! And the store used to be good, but recently the seller is very negligent about packing and protecting parcels. This is not my first order in this store. Orders I made before, the seller sent instantly, and packed very well. Therefore, definitely deserved 5 stars. But this order was shipped without any protection! That is, the seller just put my relay in a simple postal package and sent. As a result, the relay was delivered in a miracle without damage. But the package from the relay is all torn and crumpled-probably my parcel at the Post Office played football. Therefore, I shoot 2 stars. In addition, on the internet there are reviews about this store-before were only good reviews, but now buyers write that the seller sends all the parcels without protection, and the goods are delivered delivered delivered So I will not buy in this store again! I 'd better buy the goods in another store where the order is well packed and I'll be sure the goods will be delivered whole!

Большое спасибо, это моё третье реле с Пультом, 1) поливает по проограмме две теплицы с огурцами и помидорами + создаёт дождь на участке, и четвертая функция пролив компостной кучи каждый день. 2) реле - включает элюминацию перед домом в вечернее время, в большие морозы по утрам подогревает картер автомобиля. 3) реле - будет установлено в системе отопления дома по таймеру + последовательно будут включены датчики температуры. - - - о продукции SONOFF - на данный момент установлено несколько 16 Амперных с датчиками температуры, 63 А с памятью на потребляемый ток. - - какое то количество SonoFF лежат про запас, для будущих решений.
