fake smart meter chint DDSU666 wattmeter 1.5(6) with CT 100/5A - do not buy this 

Hi all,
I bought this smart meter from aliexpress for around 80 USD from chint oficial store !
I think they sell defective products on aliespress and the good ones to huawei inverter division!
It turned out to be a useless thing.
The real power is 1890W and it indicates 89W.
The Chinese don't want to give me any return, i send to them clips and demonstrate that is not good, but no help from aliiexpress...lost the money.
I threw 80 usd out the window.
Unusable, do not buy this model.
